Description

Technical Field

[0001] The invention belongs to the field of cable production, and relates to a steel belt armoring guide technology, in particular to a steel belt guide device and a steel belt armoring machine based on cable production. Background Art

[0002] The steel belt armoring machine is a necessary equipment for cable plants to produce power cables, plastic cables, and control cables. At present, the belt guide device of the steel belt armoring machine usually includes two guide roller assemblies and a deflection roller assembly independently arranged on the rotating body. The specific belt guide and armoring process are as follows: the steel belt on the belt reel is passed through the guide roller assembly, and then passed out through the deflection roller assembly, and then the steel belt and the rotating body are manually connected to the winding core that is set coaxially and keeps relative rotation, and finally the rotating body is controlled to rotate and the belt reel is controlled to convey the steel belt, and the winding core is fed relative to the rotating body along its axial direction, and the armoring of the winding core is completed.

[0003] In the above steps, in order to meet the overlap rate required for the steel belt armoring, to prevent the occurrence of warping and other situations, and thus to ensure the quality of the armoring, it is necessary to manually control the deflection roller assembly to move and drive the steel belt to twist, so as to ensure that the cutting position and cutting angle of the steel belt are accurate, thereby ensuring the quality of the armoring. Among them, when the deflection roller assembly moves to the specified position, in order to facilitate the operator to pull the steel belt through the deflection roller assembly, the guide roller assembly is usually moved to the top of the deflection roller assembly, that is, the two are located in the same vertical plane, so that the steel belt can be vertically inserted into the deflection roller assembly when it passes through the guide roller assembly, so as to facilitate the operator to pull the steel belt and increase the production rate. However, in the prior art, the guide roller assembly and the deflection roller assembly are both independently arranged, so in the process of adjusting the guide roller assembly to move to the same vertical plane as the deflection roller assembly, it takes a long time, which increases the labor intensity and also affects the overall rate.

[0004] Therefore, a steel belt guiding device and a steel belt armoring machine based on cable production are needed to solve the above problems. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a steel belt guiding device and a steel belt armoring machine based on cable production, so as to omit the operation step of adjusting the guide roller assembly to be in the same vertical plane as the deflection roller assembly, thereby saving the time required for adjustment, reducing the labor intensity of operators and improving the cable armoring rate. The present invention sets a mobile bracket and integrates the guide roller assembly and the deflection roller assembly on the mobile bracket, so that when the mobile 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 cut-in position while ensuring that the guide roller assembly is always in the same vertical plane as the deflection roller assembly, so that the operation step of adjusting the guide roller assembly to be in the same vertical plane as the deflection roller assembly can be omitted, so as to save the time required for adjustment, reducing the labor intensity of operators and improving the cable armoring rate.

[0006] To achieve the above-mentioned object, a first aspect of the present invention provides a steel belt guiding device, comprising a guide rail plate, a movable bracket, a guide roller assembly and a deflection roller assembly;

[0008] Therefore, the guide roller assembly and the deflection roller assembly are respectively fixedly mounted on one upper surface and one lower surface of the movable bracket, so that the guide roller assembly and the deflection roller assembly remain relatively fixed;

[0009] The deflection roller assembly includes a fixed block, a base and a rotating seat;

[0012] The rotating seat is rotatably mounted on the upper surface of the base and is capable of self-locking, and has two symmetrically arranged twisting rollers built therein.

[0013] Furthermore, a belt entry gap is formed between the two twisting rollers;

[0014] The belt entry gap can be located in the same vertical plane as the belt exit direction of the guide roller assembly through the movement of the base and the rotation of the rotating base.

[0015] Furthermore, the guide rail plate includes a first fixed plate and a second fixed plate arranged in parallel and a U-shaped sliding seat;

[0016] The U-shaped sliding seat is slidably mounted on the first fixed plate in a horizontal direction;

[0018] Furthermore, a screw rod is rotatably mounted on the first fixing plate;

[0019] One end of the screw rod is threadedly penetrated through the U-shaped sliding seat, and is used to drive the U-shaped sliding seat to move in a horizontal direction and self-lock.

[0020] Furthermore, the outer surface of the U-shaped sliding seat is provided with a first fastener that abuts against or separates from the surface of the movable bracket;

[0021] A second fastener is provided between the second fixing plate and the movable bracket;

[0023] Furthermore, the second fixing plate has a limiting groove;

[0024] The second fastener comprises a threaded column and a nut movably mounted inside the limiting groove;

[0025] One end of the threaded column passes through the limiting groove and the waist-shaped groove in sequence;

[0045] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1

[0047] See also Figures 1 to 4 As shown, an embodiment of the first aspect of the present invention provides a steel belt guiding device, including a guide rail plate 1, a movable bracket 2, a guide roller assembly 3 and a deflection roller assembly 4.

[0048] The movable bracket 2 is movably mounted on the guide rail plate 1 to move relative to the guide rail plate 1 in the vertical and horizontal directions and can be self-locking. The movable bracket 2 is provided to integrate the guide roller assembly 3 and the deflection roller assembly 4 together, and the deflection roller assembly 4 is moved by moving the movable bracket 2 in the horizontal and vertical directions to adjust the steel strip cutting position, so as to ensure that the armoring requirements can be met and that warping and the like will not occur.

[0049] Specifically, the guide roller assembly 3 and the deflection roller assembly 4 are respectively fixedly mounted on one upper surface and one lower surface of the movable bracket 2, 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 be vertically penetrated from the guide roller assembly 3 into the deflection roller assembly 4, thereby achieving the purpose of facilitating the operator to pull the steel belt.

[0050] In this embodiment, a specific deflection roller assembly 4 is provided to better adjust the cutting position and cutting angle of the steel strip.

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

[0052] The fixing block 41 is fixedly mounted on the outer side wall of the movable bracket 2 .

[0053] The base 42 is slidably connected to the fixing block 41 and can move and self-lock along the length direction of the fixing block 41 .

[0054] It should be noted that the length direction of the fixed block 41 is perpendicular to the outer surface of the movable bracket 2. Therefore, a three-axis displacement stage structure can be formed between the movable bracket 2, the movable bracket 2 and the guide plate 1, so that the base 42 can move in the X-axis, Y-axis and Z-axis directions, so as to better facilitate the operator to adjust the cutting position of the steel belt.

[0055] In addition, the rotating seat 43 is rotatably mounted on the upper surface of the base 42 and can be self-locking, and has two symmetrically arranged torsional rollers 431 built therein, and the cutting angle of the steel strip is adjusted by changing the angle of the torsional rollers 431.

[0056] It should be noted that a limiting roller (not numbered in the figure) is also provided on the rotating seat 43. The limiting roller is arranged in parallel with the twisting roller 431 and is located below the two twisting rollers 431 for guiding the connection between the steel strip and the winding core.

[0057] Therefore, by setting up a deflection roller assembly 4 including a fixed block 41, a base 42 and a rotating seat 43, it is possible to cooperate with the movable bracket 2 to move in the horizontal direction and the vertical direction on the guide plate 1 to realize the movement of the rotating seat 43 in the three-axis direction and the rotation around the vertical direction, so as to facilitate the operator to adaptively adjust the cutting position and the cutting angle between the steel strip and the winding core, so as to achieve the purpose of improving the armor quality.

[0058] The device is provided with a movable bracket 2, and the guide roller assembly 3 and the deflection roller assembly 4 are respectively fixedly mounted on the upper and lower surfaces of the same side of the movable bracket 2. When it is necessary to drive the deflection roller assembly 4 to adjust the steel belt cutting position, the operator can complete it by moving the movable bracket 2 along the direction of the guide rail plate 1. Therefore, at this time, the guide roller assembly 3 can move 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 the adjustment, thereby achieving the purpose of reducing the labor intensity of the operator and improving the cable armoring rate.

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

[0060] Specifically, a scale and an angle scale are respectively disposed on the upper surface of the fixed block 41 and the upper surface of the base 42. Wherein, both the base 42 and the rotating base 43 have pointers corresponding to the scale and the angle scale.

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

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

[0063] like Figure 2 As shown, it should be particularly noted that, in this embodiment, a belt entry gap is formed between the two twisting rollers 431.

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

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

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

[0067] The U-shaped sliding seat 13 is slidably installed on the first fixed plate 11 along the horizontal direction, that is, the U-shaped sliding seat 13 moves horizontally on the first fixed plate 11 to drive the movable bracket 2 to move, thereby correspondingly driving the movement of the deflection roller assembly 4 on the movable bracket 2.

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

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

[0070] A screw rod 111 is rotatably mounted on the first fixing plate 11, and one end of the screw rod 111 is threadedly penetrated through the U-shaped sliding seat 13, and is used to drive the U-shaped sliding seat 13 to move horizontally and self-lock. That is, the U-shaped sliding seat 13 is driven to feed by the rotation of the screw rod 111, thereby completing the movement control of the mobile bracket 2.

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

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

[0073] In addition, a second fastener 6 is provided between the second fixed plate 12 and the movable bracket 2. Accordingly, in order to prevent the second fastener 6 on the second fixed plate 12 from interfering with the vertical movement of the movable bracket 2, a waist-shaped groove 21 matching the second fastener 6 is also provided on the outer wall of the movable bracket 2, so that the movable bracket 2 can move in the vertical direction relative to the second fixed plate 12.

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

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

[0076] One end of the threaded column 61 passes through the limiting groove 121 and the waist-shaped groove 21 in sequence, and the nut 62 is threadedly installed on the outer wall of the threaded column 61 to be tightly attached to or separated from the movable bracket 2, that is, the fixation between the movable bracket 2 and the second fixed plate 12 or the relative movement in the vertical direction and the horizontal direction are respectively completed by the tight attachment or separation of the nut 62 and the movable bracket 2, thereby realizing the position adjustment and self-locking functions of the deflection roller assembly 4 on the movable bracket 2.

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

[0078] In a further embodiment, the guide roller assembly 3 is further defined to improve the stability of the steel strip during feeding and conveying. Specifically, the guide roller assembly 3 includes at least two guide roller bodies, and the steel strip is wound around the outer walls of the plurality of guide roller bodies in an S shape.

[0079] Embodiment 2

[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 belt armoring machine based on cable production includes a frame 7, a rotating body 8, a belt reel 9 and the steel belt 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 guiding 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, and 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 operators and improving the cable armoring rate.

[0085] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. 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.
