Description

TECHNICAL FIELD

[0001] The present application belongs to the field of cable production, and relates to a steel tape armoring lead-through technology, in particular to a steel tape lead-through device and a steel tape armoring machine based on cable production. BACKGROUND

[0002] The steel tape armoring machine is a necessary equipment for power cable, plastic cable and control cable in a cable factory. At present, the lead-through device of the steel tape armoring machine usually comprises two guide roller assemblies and a deflection roller assembly which are independently arranged on a rotating body. The specific lead-through and armoring process is as follows: the steel tape on the tape reel is threaded through the guide roller assembly, and then threaded out of the deflection roller assembly, and then the steel tape is connected with a winding core which is arranged coaxially and relatively rotatable with the rotating body by manual operation, and finally the rotating body is controlled to rotate and the tape reel is controlled to convey the steel tape, and the winding core is fed along the axial direction of the rotating body, so that the armoring of the winding core is completed.

[0003] In the above steps, in order to meet the lap joint rate required by the steel tape armoring, prevent the occurrence of edge lifting and other situations, and ensure the armoring quality, it is necessary to manually control the deflection roller assembly to move and twist the steel tape to ensure the accurate cutting-in position and cutting-in angle of the steel tape, thereby ensuring the armoring quality. When the deflection roller assembly moves to the specified position, in order to facilitate the operator to pull the steel tape through the deflection roller assembly, the guide roller assembly is usually moved to the upper side of the deflection roller assembly, i.e. both are located in the same vertical plane, so that the steel tape can be vertically threaded into the deflection roller assembly when threaded out of the guide roller assembly, thereby facilitating the operator to pull the steel tape and improving the production rate. However, in the prior art, the guide roller assembly and the deflection roller assembly are independently arranged, so that it takes a long time to adjust the guide roller assembly to move to the same vertical plane as the deflection roller assembly, which increases the labor intensity and also affects the overall rate.

[0004] Therefore, there is a need for a steel tape lead-through device and a steel tape armoring machine based on cable production to solve the above problems. SUMMARY

[0005] The present application aims to at least solve one of the technical problems existing in the prior art; for this purpose, the present application proposes a steel belt guiding device and a steel belt armoring machine based on cable production to omit the operation step of adjusting the movement of the guide roller assembly to be in the same vertical plane as the deflection roller assembly, thereby saving the time required for adjustment and reducing the labor intensity of the operator and improving the cable armoring speed. The present application sets a moving bracket, and integrates the guide roller assembly and the deflection roller assembly on the moving bracket, so that when the moving bracket moves, it can synchronously drive the guide roller assembly and the deflection roller assembly to move, so that the deflection roller assembly moves to adjust the cutting-in position while ensuring that the guide roller assembly is always in the same vertical plane as the deflection roller assembly, thereby omitting the operation step of adjusting the movement of the guide roller assembly to be in the same vertical plane as the deflection roller assembly, thereby saving the time required for adjustment and reducing the labor intensity of the operator and improving the cable armoring speed.

DETAILED DESCRIPTION

[0045] The technical solutions of the present application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0046] Embodiment one

[0047] Please refer to Figures 1 to 4 The first aspect of the present application provides a steel belt guiding device, which comprises a guide rail plate 1, a moving support 2, a guide roller assembly 3 and a deflection roller assembly 4.

[0048] The moving support 2 is movably installed on the guide rail plate 1 to move in the vertical direction and the horizontal direction relative to the guide rail plate 1 and can be self-locked. By setting the moving support 2 to integrate the guide roller assembly 3 and the deflection roller assembly 4 together, the movement of the deflection roller assembly 4 is completed by the movement of the moving support 2 in the horizontal direction and the vertical direction, thereby realizing the adjustment of the steel belt cutting-in position to ensure that the armored requirement can be met and the edge lifting and other situations can be avoided.

[0049] Specifically, the guide roller assembly 3 and the deflection roller assembly 4 are fixedly installed on the upper surface and the lower surface of one side of the moving support 2 respectively, so that the guide roller assembly 3 and the deflection roller assembly 4 remain relatively fixed, that is, the guide roller assembly 3 and the deflection roller assembly 4 are located in the same vertical plane, so that the steel belt can enter the deflection roller assembly 4 in a vertical manner by the guide roller assembly 3, thereby achieving the purpose of facilitating the operator to pull the steel belt.

[0050] In the present embodiment, a specific deflection roller assembly 4 is proposed to better adjust the cutting-in position and the cutting-in angle of the steel belt.

[0051] Specifically, the deflection roller assembly 4 comprises a fixed block 41, a base 42 and a rotating seat 43.

[0052] The fixed block 41 is fixedly installed on the outer side wall of the moving support 2.

[0053] The base 42 is in sliding connection with the fixed block 41 and can move and self-lock along the length direction of the fixed block 41.

[0054] It should be noted that the length direction of the fixed block 41 is perpendicular to the outer surface of the moving support 2. Therefore, the moving support 2, the moving support 2 and the guide rail plate 1 form a three-axis displacement table structure, so that the base 42 moves in the X-axis, Y-axis and Z-axis directions, to better facilitate the operator to adjust the cutting-in position of the steel belt.

[0055] In addition, the rotating seat 43 is rotatably installed on the upper surface of the base 42 and can self-lock, and two symmetrical torsion rollers 431 are built-in. The adjustment of the steel belt cutting-in angle is completed by the angle change of the torsion rollers 431.

[0056] It should be noted that the rotating seat 43 is also provided with a limiting roller (not labeled in the figure), which is arranged in parallel with the torsion roller 431 and located below the two torsion rollers 431, for guiding the connection of the steel belt and the winding core.

[0057] Therefore, by arranging the deflection roller assembly 4 including the fixed block 41, the base 42 and the rotating seat 43, the movement of the rotating seat 43 in the three-axis direction and the rotation around the vertical direction can be realized by cooperating with the movement of the moving support 2 on the guide rail plate 1 in the horizontal direction and the vertical direction, thereby facilitating the operator to adaptively adjust the cutting-in position and the cutting-in angle between the steel belt and the winding core, and achieving the purpose of improving the armored quality.

[0058] The device is provided with the moving support 2, and the guide roller assembly 3 and the deflection roller assembly 4 are fixedly installed on the upper and lower surfaces of the same side of the moving support 2, respectively. Therefore, when the deflection roller assembly 4 needs to be driven to adjust the steel belt cutting-in position, the operator can complete it by moving the moving support 2 along the guide rail plate 1. At this time, the guide roller assembly 3 can move synchronously with the deflection roller assembly 4, so that the out belt direction of the guide roller assembly 3 and the in belt direction of the deflection roller assembly 4 are always located in the same vertical plane, thereby omitting the operation step of adjusting the guide roller assembly 3 to be located in the same vertical plane with the deflection roller assembly 4, to correspondingly save the time required for adjustment, to reduce the labor intensity of the operator and to improve the cable armored speed.

[0059] In other embodiments, in order to improve the adjustment accuracy of the steel belt cutting-in position and the cutting-in angle, the fixed block 41, the base 42 and the rotating seat 43 are further limited.

[0060] Specifically, the upper surface of the fixed block 41 and the upper surface of the base 42 are respectively provided with a scale and an angle scale. Among them, the base 42 and the rotating seat 43 are provided with a pointer corresponding to the scale and the angle scale.

[0061] It should be noted that the sliding connection between the fixed block 41 and the base 42 is provided with a positioning pin, and the base 42 is also provided with a key slot type through hole, and the self-locking function is realized by tightening the positioning pin.

[0062] And the rotating seat 43 and the base 42 are limited by screws, that is, when the rotating seat 43 is rotated to a specific angle relative to the base 42, the rotating seat 43 and the base 42 are fixed by screws to ensure that the steel belt will not loosen during guiding, and to ensure that the steel belt cutting angle always remains unchanged, and to ensure the armor quality.

[0063] As shown in Figure 2 It should be noted that in this embodiment, the two torsion rollers 431 form a belt entry gap.

[0064] Among them, as shown by the dashed line in Figure 2 The belt entry gap can be in the same vertical plane as the belt exit direction of the guide roller assembly 3 by moving the base 42 and rotating the rotating seat 43.

[0065] In further embodiments, the guide rail plate 1 is further limited to facilitate position adjustment and self-locking of the deflection roller assembly 4.

[0066] Specifically, the guide rail plate 1 includes a first fixed plate 11 and a second fixed plate 12 arranged in parallel, and a U-shaped sliding seat 13.

[0067] Among them, the U-shaped sliding seat 13 is slidably installed on the first fixed plate 11 along the horizontal direction, that is, by moving the U-shaped sliding seat 13 on the first fixed plate 11 along the horizontal direction, the moving bracket 2 is driven to move, and in turn the moving bracket 2 and the deflection roller assembly 4 on the moving bracket 2 are driven to move.

[0068] The moving bracket 2 penetrates the U-shaped sliding seat 13 along the vertical direction, and is movably connected with the second fixed plate 12, that is, the moving bracket 2 can move in the vertical direction relative to the first fixed plate 11 and the second fixed plate 12.

[0069] Therefore, by moving the moving bracket 2 in the horizontal direction and the vertical direction, the position of the deflection roller assembly 4 is changed to adjust the steel belt cutting position.

[0070] The first fixed plate 11 is provided with a screw rod 111, one end of the screw rod 111 is screwed through the U-shaped sliding seat 13, and the U-shaped sliding seat 13 is driven to move in the horizontal direction and is self-locked. That is, the U-shaped sliding seat 13 is driven to feed by rotating the screw rod 111, so as to complete the movement control of the moving support 2.

[0071] It should be noted that in order to ensure that the U-shaped sliding seat 13 can drive the moving support 2 to move synchronously when the U-shaped sliding seat 13 moves, the U-shaped sliding seat 13 is further limited, so that the U-shaped sliding seat 13 and the moving support 2 can be connected as a whole or relatively move in the vertical direction.

[0072] Specifically, the outer surface of the U-shaped sliding seat 13 is provided with a first fastener 5 which abuts or separates from the surface of the moving support 2.

[0073] In addition, the second fixed plate 12 and the moving support 2 are provided with a second fastener 6, and correspondingly, in order to prevent the second fastener 6 on the second fixed plate 12 from interfering with the movement of the moving support 2 in the vertical direction, a waist-shaped groove 21 matched with the second fastener 6 is further arranged on the outer wall of the moving support 2, so that the moving support 2 can move in the vertical direction relative to the second fixed plate 12.

[0074] The second fixed plate 12 has a limiting groove 121.

[0075] The second fastener 6 includes a threaded column 61 movably installed in the limiting groove 121 and a nut 62.

[0076] One end of the threaded column 61 is sequentially threaded through the limiting groove 121 and the waist-shaped groove 21, and the nut 62 is threaded on the outer wall of the threaded column 61 to abut or separate from the moving support 2. That is, the nut 62 and the moving support 2 are abutted or separated to respectively complete the fixing between the moving support 2 and the second fixed plate 12 or the relative movement in the vertical direction and the horizontal direction, so as to realize the function of position adjustment and self-locking of the deflection roller assembly 4 on the moving support 2.

[0077] In other embodiments, the first fixed plate 11 and the second fixed plate 12 are both provided with a plurality of connecting pieces (not numbered in the figure) fixed to external components. In one example, the connecting pieces are screws.

[0078] In further embodiments, the guide roller assembly 3 is further limited to improve the stability of the steel belt feeding and conveying. Specifically, the guide roller assembly 3 includes at least two guide roller bodies, and the steel belt is wound in an S shape on the outer walls of the guide roller bodies.

[0079] Embodiment two

[0080] like Figure 5 As shown, this embodiment further proposes a steel strip armoring machine based on cable production on the basis of the first embodiment, so as to improve the rate of cable armoring production.

[0081] Specifically, a steel tape armoring machine based on cable production includes a frame 7, a rotating body 8, a tape reel 9 and the steel tape guiding device described in the first embodiment (as shown in the dotted box in the figure).

[0082] The rotating body 8 is rotatably mounted on the frame 7 .

[0083] The belt reel 9 and the steel belt guide device are both fixedly mounted on one side of the rotating body 8 .

[0084] By integrating the guide roller assembly 3 and the deflection roller assembly 4 on the movable bracket 2, and fixing the guide plate 1 on the outside of the rotating body 8, the positional relationship between the deflection roller assembly 4 and the rotating body 8 can be changed by moving the movable bracket 2 to complete the adjustment of the steel belt cutting position. In this process, the guide roller assembly 3 always moves synchronously with the deflection roller assembly 4, so that the belt-out direction of the guide roller assembly 3 and the belt-in direction of the deflection roller assembly 4 are always located in the same vertical plane, thereby omitting the operation step of adjusting the guide roller assembly 3 to move to the same vertical plane as the deflection roller assembly 4, thereby saving the time required for adjustment, thereby achieving the purpose of reducing the labor intensity of the operator and improving the cable armoring rate.

[0085] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
