Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a concentric steel belt armoring steel belt unwinding disk. Background Art

[0002] Armored cable refers to a cable with a metal protective layer wrapped with steel tape on the outermost layer to protect the cable from external mechanical damage. It is like putting armor on the cable, so it is called armored cable.

[0003] In the production of armored cables, the steel strips are rolled and packaged after being produced by upstream manufacturers. The steel strips are rolled into discs for easy transportation. However, in order to save transportation costs, upstream manufacturers roll the steel strips into large rolls. However, in production, large rolls of steel strips are too large and heavy to be directly loaded onto machines. Therefore, companies usually rewind the large rolls of steel strips in sections on steel strip pay-off reels, and then use the steel strip pay-off reels to armor the cables. However, after rewinding, the steel strips need to be packaged with steel wire to prevent them from loosening. Traditional straight-cylinder steel strip pay-off reels are not convenient for packaging with steel wire.

[0004] In order to solve the above problems, a patent document with application number 202221292950.2 discloses a steel strip reel for armored cables, whose structure includes a movable base, a second vertical plate is vertically installed on the top surface of the movable base, a support plate is arranged on the outer surface of the second vertical plate, a driving motor is installed on the top surface of the support plate, a main shaft is arranged through the output end of the driving motor through the surface of the second vertical plate, a reel body is arranged at one end of the main shaft, a yield path is arranged through the outer surface of the reel body, a fan-shaped plate is vertically arranged on the outer surface of the reel body, and a sealed bearing is installed at the contact point between the main shaft and the second vertical plate. By setting the yield path and the fan-shaped plate for use together, after the steel strip is rolled up, the staff can use wire or cable ties to bypass the gap between the yield path and the fan-shaped plate, so as to bundle the rolled steel strip.

[0005] The above patent can usually solve the problem of bundling steel strips, but the steel strip pay-off reel mainly presses against the inner cavity surface of the steel strip pay-off reel through an outwardly retractable fixed plate, and uses the friction between the fixed plate and the inner cavity surface to fix the steel strip pay-off reel. However, when the steel strip is reeled or wrapped around the cable, a certain tension is required to make the steel strip taut, and the reeled steel strip and cable wrapping will be tighter. The steel strip pay-off reel in the prior art has a smooth inner wall like the winding reel in the above patent. When the rotation speed during rewinding or cable wrapping is increased, the tension generated by the steel strip becomes larger, the steel strip pay-off reel and the fixed plate are easy to slip, the steel strip becomes loose, and the tension of the steel strip needs to be readjusted, resulting in intermittent production. Utility Model Content

[0006] The purpose of the utility model is to provide a concentric steel belt pay-off drum for steel belt armor, so as to solve the technical problem that the steel belt pay-off drum in the prior art mentioned above has a smooth inner wall and an unlimited structure, which is easy to slip when matched with a fixed plate that telescopes outward, causing the steel belt to become loose and requiring readjustment of the tension of the steel belt.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a concentric steel strip armored steel strip unwinding reel, comprising a straight cylindrical winding body and baffles fixedly connected at both ends of the winding body, a bundling notch is opened on the straight cylindrical structure of the winding body, and a corresponding notch is also provided on the baffle at the bundling notch, and a limit strip is provided on the inner cavity surface of the winding body near the boundary position of the bundling notch.

[0008] The beneficial effects of this embodiment are:

[0009] 1. Compared with the prior art, the inner surface of the winding body of the present application is provided with a limit strip. During rewinding, the outwardly retracted fixed plate is retracted outward by relying on the limit strip, and then pressed against the inner surface of the winding body. Since the limit strip limits the circumferential position of the fixed plate, the fixed plate is limited by the limit strip during rewinding, and is not easy to slip, thereby maintaining the stable tension of the steel belt.

[0010] 2. In the prior art, the clearance road and the fan-shaped plate need to be used together so that after the steel strip is rolled up, the staff can use the binding wire or the binding tie to bypass the gap between the clearance road and the fan-shaped plate to bundle the rolled steel strip. However, in the present application, a binding notch is provided, and after the steel strip is rewound, the binding wire or the binding tie can be directly used to bundle the steel strip roll at the binding notch, which has a simpler structure and is more convenient to operate.

[0011] 3. Since a bundling notch is designed in this application, but the bundling notch causes the structure of the steel strip pay-off drum to be destroyed, a limit strip is set close to the bundling notch, and the limit strip is used to reinforce the strength of the bundling notch to avoid deformation of the steel strip pay-off drum structure.

[0012] Furthermore, a fixing hole for fixing the steel strip head is provided on the winding body between the limit strip and the bundling notch, so as to facilitate fixing the steel strip head during rewinding.

[0013] Furthermore, the baffle is a shell structure with strip-shaped drum shells evenly arranged on the surface circumferentially. The shell structure makes the overall mass of the tape reel of the present application small, and is convenient for workers to take and put.

[0014] Furthermore, a rectangular block is provided on the baffle plate to enhance the rigidity of the shell structure.

[0015] Furthermore, the limiting strip is a rectangular solid steel strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural schematic diagram of an embodiment of the utility model,

[0017] Figure 2 This is the front view of the embodiment of the utility model.

[0018] Figure 3 It is a right side view of an embodiment of the utility model. DETAILED DESCRIPTION

[0019] The following is further described in detail through specific implementation methods:

[0020] The reference numerals in the drawings of the specification include: baffle 1, strip drum shell 11, rectangular block 12, arc block 13, winding body 2, inner cavity 21, limit strip 22, steel belt fixing port 23, bundling notch 3, steel belt 4, steel belt head 41.

[0021] Implementation example Figures 1 to 3 As shown: a concentric steel strip armor steel strip unwinding reel includes a winding body 2, the winding body 2 has a straight cylindrical structure, a notch is opened on the straight cylindrical structure of the winding body 2, the notch penetrates the winding body 2 horizontally, baffles 1 are welded at both ends of the winding body 2, the cross-section of the baffle 1 is a notched circular ring structure, the notch of the baffle 1 coincides with the notch on the winding body 2, and the two notches together constitute a bundling notch 3, the bundling notch 3 makes the steel strip 4 wound on the winding body 2 partially exposed, so the rewound steel strip 4 can be directly bundled with a tie tie or a tie wire.

[0022] The baffle 1 is a shell structure made of metal sheet. The shell structure reduces the mass of the baffle 1 and facilitates later removal and placement. However, the strength of the shell structure is insufficient. Therefore, a plurality of strip drum shells 11 are equidistantly provided on the baffle 1 along the circumference of the center of the circular cross-section of the baffle. The strip drum shells 11 are equidistantly provided along the circumference of the baffle 1. The raised structure on the baffle 1 is used to enhance the overall rigidity of the baffle. Rectangular blocks 12, arc blocks 13 and other rigidity-enhancing structures are also provided near the notch of the baffle 1.

[0023] The winding body 2 is a straight tube structure with a notch, and its inner cavity 21 is provided with limit strips 22 at both ends near the bundling notch 3. The limit strip 22 is a solid rectangular strip made of steel, which is fixed to the inner cavity 21 by welding. Therefore, when the fixed plate extends into the center of the inner cavity 21 and expands outward to press against the inner cavity 21, the operator should pay attention to the edge of the fixed plate against the limit strip 22, so that the limit strip 22 in the circumferential direction will limit the fixed plate, so that the fixed plate will not slide relative to the steel strip pay-off drum when driving it to rotate. In addition, the bundling notch 3 damages the structure of the steel strip pay-off drum. The limit strip 22 is set close to the bundling notch 3 to strengthen the rigidity of the bundling notch 3 and prevent the steel strip pay-off drum from deforming.

[0024] A steel belt fixing opening 23 with a width larger than that of the steel belt is provided between the limiting strip 22 and the edge of the inner cavity 21 near the bundling notch 3. The steel belt fixing opening 23 penetrates the winding body 2 to form a rectangular through-hole structure. When rewinding, the steel belt head 41 can be first passed through the steel belt fixing opening 23 to be bent and fixed, and the steel belt is tensioned by stretching so that the rewound steel belt is tight.

[0025] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
