Description

Technical Field

[0001] The utility model relates to the technical field of coiled material reeling and unreeling, in particular to a winding drum core bracket Background Art

[0002] Coiled materials refer to materials that are wound into rolls on winding cores for storage. In order to protect the coiled materials from loosening, falling off or collision damage during transportation and storage, covers are often provided on both sides of the coiled materials to protect them. In the field of coiled material manufacturing, various winding and unwinding processes are often involved. For example, in the step of slitting a wide coiled material into narrow strips, the winding core of the wide coiled material needs to be placed on the core support first, and then the unwinding and slitting steps are performed.

[0003] However, wide coils are often unevenly wound, which results in the cover plates on both sides of the unrolled coil being unable to be completely clamped. When the coil begins to be unrolled and slit, as its own weight continues to decrease, the coil is prone to idling on the core support, causing the coil to fall off or shake, resulting in the breakage of the slit strip and other problems. Summary of the invention

[0004] In order to overcome the defects in the prior art, a winding core support is provided, so that the winding core of the coil can be firmly fixed on the core support during the whole unwinding process to avoid idling.

[0005] The technical solution of the utility model is as follows: a winding core bracket, comprising a main bracket, a tensioning mechanism and an adjusting mechanism; the tensioning mechanism and the adjusting mechanism are assembled on a central bearing provided on the main bracket, and the two ends of the central bearing are equipped with a first baffle and a second baffle for positioning the winding core; the tensioning mechanism comprises a first positioning wheel, a second positioning wheel and a plurality of telescopic connecting rods assembled between the first positioning wheel and the second positioning wheel for tensioning the winding core; the adjusting mechanism is used to adjust the telescopic extension of the telescopic connecting rod.

[0006] When the adjustment mechanism adjusts the telescopic connecting rod to be in a retracted state, the telescopic connecting rod abuts against the inner wall of the winding core, increasing the friction between the telescopic connecting rod and the winding core. At this time, the winding core is in a tensioned state to prevent idling during the unwinding process of the coiled material. When the adjustment mechanism adjusts the telescopic connecting rod to be in an extended state, the telescopic connecting rod is away from the inner wall of the winding core. At this time, the winding core is in a relaxed state, which is convenient for unloading the winding core. The degree of tension of the above-mentioned telescopic connecting rod on the winding core can also be expressed by the magnitude of the tensioning force.

[0007] Preferably, the telescopic connecting rod comprises a first connecting rod, a second connecting rod and a middle bearing; the first connecting rod and the second connecting rod are rotatably connected around the middle bearing. The above connection structure enables the change of the connection angle of the first connecting rod and the second connecting rod to drive the middle bearing to move toward the central bearing or outward (away from the central bearing), thereby achieving a tensioned or relaxed state of the winding core.

[0008] Preferably, the first connecting rod and the second connecting rod are hinged to the first positioning wheel and the second positioning wheel respectively. Through the hinge connection mode, the positioning wheel has a certain buffering and adaptability when subjected to external force, reducing the impact and damage to the entire support structure.

[0009] Preferably, the centers of the first positioning wheel and the second positioning wheel are both provided with connecting holes that match the diameter of the center bearing, so that the positioning wheels can be mounted on the center bearing and are not prone to displacement, thereby improving the structural stability of the entire core bracket and ensuring that the positioning wheels can remain stable when rotating or adjusting.

[0010] Preferably, the adjustment mechanism includes an elastic adjustment block and a spring; the elastic adjustment block is sleeved on the central bearing between the first positioning wheel and the second positioning wheel, and the spring is sleeved on the central bearing between the second positioning wheel and the second baffle. Through the coordinated action of the elastic adjustment block and the spring, the adjustment mechanism can control the tensioning force of the cylinder core bracket. The elastic adjustment block is used to adjust the pressure of the spring on the second positioning wheel, thereby driving the extension and retraction of the telescopic connecting rod to achieve the purpose of adjusting the tensioning force of the tensioning mechanism. The adaptability and stability of the cylinder core bracket are improved, and the operation is made more convenient and efficient.

[0011] As another embodiment, the spring is sleeved on the central bearing between the first positioning wheel and the first baffle. Through the coordinated action of the elastic force adjustment block and the spring, the adjustment mechanism can realize the control of the tensioning force of the cylinder core bracket. The elastic force adjustment block is used to adjust the pressure of the spring on the first positioning wheel, thereby driving the extension and retraction of the telescopic connecting rod to achieve the purpose of adjusting the tensioning force of the tensioning mechanism.

[0012] Preferably, a plurality of support bars are equidistantly arranged between the first baffle and the second baffle along the boundary of the first baffle. The support bars are equidistantly distributed along the boundary of the first baffle to form a stable support frame. This helps to prevent the first baffle and the second baffle from being deformed or displaced when subjected to external force, thereby improving the stability of the entire barrel core support.

[0013] Preferably, the diameter of the first baffle plate matches the inner diameter of the winding core. The first baffle plate can be closely attached to the inner wall of the core, thereby preventing the core from shifting or shaking during winding or processing.

[0014] Preferably, the diameter of the second baffle matches the initial diameter of the coil on the winding core. The second baffle can provide a stable support surface so that the initial winding layer of the coil can fit tightly and evenly on the core, which is convenient for positioning and fixing the coil.

[0015] Preferably, the plurality of telescopic connecting rods are evenly distributed circumferentially around the central bearing.

[0016] Preferably, there are three shrinkage connecting rods evenly distributed circumferentially, so as to facilitate the uniform tightening of the winding core by the middle bearing.

[0017] Preferably, the first baffle is fixed to the central bearing by bolt connection. Bolt connection is a common and effective fixing method, which can achieve a tight connection between the first baffle and the central bearing. Ensure that the connection has sufficient strength and stability to withstand the weight of the core and the coil, as well as the vibration and impact during operation.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] A winding core bracket can achieve tensioning of the winding core through the cooperation of a tensioning mechanism and an adjusting mechanism to prevent the coil from idling on the core bracket; and the main body bracket serves as the basic frame of the entire core bracket, carrying and supporting other components, wherein the center bearing is located at the center of the main body bracket, and the first baffle plate and the second baffle plate are respectively assembled at the two ends of the center bearing to position and fix the winding core to ensure that it does not move or shake during operation.

DETAILED DESCRIPTION

[0026] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0027] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0028] like Figure 1 to Figure 2 As shown, the core support includes a main support 1, a tensioning mechanism 2 sleeved on the main support, and an adjusting mechanism 3 for adjusting the tensioning force of the tensioning mechanism 2. The main support includes a central bearing 1-4, a first baffle 1-1 and a second baffle 1-2 assembled at both ends of the central bearing 1-4, and a plurality of support bars 1-3 equidistantly arranged between the two baffles around the boundary of the first baffle 1-2.

[0029] The diameter of the first baffle 1-1 is equivalent to the inner diameter of the winding core of the coil, and the diameter of the second baffle 1-2 is equivalent to the initial diameter of the coil. When the winding core is sleeved on the main support 1, the surface of the cover plate on one side thereof abuts against the second baffle 1-2, which is convenient for positioning and fixing the coil. The first baffle 1-1 is connected and fixed to the central bearing 1-4 by bolts 1-5, so that the entire main support 1 becomes a solid whole.

[0030] The tensioning mechanism 2 includes a first positioning wheel 2-1 and a second positioning wheel 2-2 which are sleeved on the center bearing 1-4 through a connecting hole 2-4 which matches the diameter of the center bearing, and a telescopic connecting rod 2-3 whose two ends are hingedly fixed to the two positioning wheels, and the telescopic connecting rod 2-2 includes a first connecting rod 2-3-1, a second connecting rod 2-3-2, and a middle bearing 2-3-3 which hinges the first connecting rod and the second connecting rod.

[0031] There are multiple telescopic connecting rods 2-3, and the multiple telescopic connecting rods 2-3 are evenly distributed around the central bearing 1-4. The telescopic connecting rods 2-3 are preferably set to 3. By adjusting the telescopic state of the telescopic connecting rods 2-3, a suitable tensioning force between the middle bearing 2-3-3 and the inner wall of the winding drum core can be achieved.

[0032] Specifically, the winding core is firstly sleeved on the core bracket, and when the telescopic connecting rod 2-3 retracts, the middle bearing 2-3-3 protrudes relative to the center bearing 1-4 and abuts against the inner wall of the winding core. This is a tensioned state. In this state, the friction between the winding core and the core bracket can be increased to avoid idling. When the telescopic connecting rod 2-3 is extended, the middle bearing 2-3-3 retracts relative to the center bearing 1-4 and away from the inner wall of the winding core. This is a relaxed state, which is convenient for unloading the winding core.

[0033] Furthermore, the adjustment mechanism 3 includes an elastic adjustment block 3-1 and a spring 3-2; the elastic adjustment block 3-1 is sleeved on the central bearing 1-4 between the first positioning wheel 2-1 and the second positioning wheel 2-2, and the spring 3-2 is sleeved on the central bearing 1-4 between the second positioning wheel 2-2 and the second baffle 1-2.

[0034] When in use, the elastic force adjustment block 3-1 can be moved to make it abut against and push the second positioning wheel 2-2 to move toward the second baffle plate 1-2. The second positioning wheel 2-2 compresses the spring 3-2, increases the distance between the two positioning wheels, causes the telescopic connecting rod 2-3 to extend, and the middle bearing 2-3-3 to retract toward the center bearing 1-4. The elastic force adjustment block 3-1 can also be moved toward the side of the first baffle plate 1-1, the spring 3-2 is extended, reduces the distance between the two positioning wheels, causes the telescopic connecting rod 2-3 to retract, and the middle bearing 2-3-3 to bulge relative to the center bearing 1-4.

[0035] Furthermore, the spring 3-2 is sleeved on the central bearing 1-4 between the first positioning wheel 2-1 and the first baffle 1-1.

[0036] When in use, the elastic force adjustment block 3-1 can be moved to abut against and push the first positioning wheel 2-1 to move toward the side of the first baffle plate 1-1. The first positioning wheel 2-1 compresses the spring 3-2, increases the distance between the two positioning wheels, causes the telescopic connecting rod 2-3 to extend, and the middle bearing 2-3-3 to retract toward the inside of the central bearing 1-4; the elastic force adjustment block 3-1 can also be moved to the side of the second baffle plate 1-2, the spring 3-2 extends, reduces the distance between the two positioning wheels, causes the telescopic connecting rod 2-3 to retract, and the middle bearing 2-3-3 to bulge relative to the central bearing 1-4.

[0037] Therefore, the distance between the first positioning wheel 2-1 and the second positioning wheel 2-2 can be adjusted by the adjustment mechanism 3, thereby adjusting the telescopic state of the telescopic connecting rod 2-3, and achieving the purpose of adjusting the tensioning force of the tensioning mechanism 2. In order to facilitate the adjustment of the tensioning force, when the spring 3-2 is sleeved on the center bearing 1-4 between the second positioning wheel 2-2 and the second baffle 1-2, the first positioning wheel 2-1 is adjacent to or abuts the first baffle 1-1 and fixed on the center bearing 1-4, as long as the telescopic connecting rod 2-3 has enough telescopic space, wherein the second positioning wheel 1-2 is movably connected to the center bearing 1-4 and can slide back and forth on the center bearing 1-4; when the spring 3-2 is sleeved on the center bearing 1-4 between the first positioning wheel 2-1 and the first baffle 1-1, the second positioning wheel 2-2 is adjacent to or abuts the second baffle 1-2 and fixed on the center bearing 1-4, as long as the telescopic connecting rod 2-3 has enough telescopic space, wherein the first positioning wheel 1-1 is movably connected to the center bearing 1-4 and can slide back and forth on the center bearing 1-4.

[0038] When in use, the tensioning force can be adjusted before or after the winding core is installed. To ensure production efficiency, it is preferably adjusted before the winding core is installed. The tensioning force adjustment standard is that when the winding core is installed, it can be smoothly sleeved on the core bracket, the middle bearing 1-4 abuts against the inner wall of the core, the friction between the winding core and the core bracket is increased, and no idling occurs. When the winding core is unloaded, the middle bearing 1-4 will not form an obstacle, so that the winding core can be installed and unloaded.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
