Description

Technical Field

[0001] The present application relates to the technical field of cable production, and in particular to a paper wrapping machine. Background Art

[0002] Currently, in the production process of cables, it is necessary to wrap paper strips, such as aluminum foil or cotton paper, on the outer surface of the inner core or the outer surface of the sub-wire to achieve a shielding effect and ensure stable transmission of signals inside the cable.

[0003] Existing Chinese patent with announcement number CN213800298U discloses a paper wrapping machine for electric wire production, which includes a frame, a wire outlet device and a wire take-up device respectively arranged on both sides of the frame, the frame is provided with a first wire tube and a second wire tube through which the power line passes, the first wire tube and the second wire tube are both arranged as hollow through-hole structures, the first wire tube is provided with a carrying disk for placing the wrapping tape, the first wire tube is provided with a driving device for driving the first wire tube to rotate, and the carrying disk is provided with a clamping assembly holding rod.

[0004] Regarding the above-mentioned related technologies, when working, the cable passes vertically through the first wire tube and the second wire tube and is continuously transported upward, and the paper roll for wrapping is sleeved on the first wire tube and fixed to the supporting plate by a clamping assembly. When the paper roll is unrolled, the paper strip bypasses the holding rod and then wraps upward on the cable located outside the cable, at which time an angle is formed between the paper strip and the vertical cable. However, during the paper wrapping process, since the position of the holding rod and the vertical part of the cable between the first wire tube and the second wire tube remain unchanged, the angle position cannot be adjusted, resulting in the inability to adjust the paper wrapping efficiency and the wrapping coverage of the paper strip, which needs to be improved. Utility Model Content

[0005] In order to facilitate the adjustment of the angle between the paper strip and the wrapping portion of the vertical portion of the cable, and thereby adjust the paper wrapping efficiency and the wrapping coverage of the paper strip, the present application provides a paper wrapping machine.

[0006] The paper wrapping machine provided in this application adopts the following technical solution:

[0007] A paper wrapping machine includes a carrying plate, a guide rod and a first sleeve. The carrying plate is rotatably arranged, the first sleeve is coaxially arranged on the upper surface of the carrying plate, the guide rod is arranged on the upper surface of the carrying plate, the first sleeve is threadedly connected to a fastener for pressing a paper roll, a limit ring is movably arranged on the fastener, and the limit ring is slidably adjusted in the horizontal direction. After the paper roll is unwound, it is wrapped around the outside of the guide rod and then passes through the limit ring.

[0008] By adopting the above technical solution, the cable passes through the first sleeve vertically, and after the wrapping paper roll is sleeved on the first sleeve, the roll part of the paper roll is pressed against the carrier plate by the fastener to fix the paper roll. Then, after the carrier plate rotates to unwind the paper roll, the unwound paper strip bypasses the guide rod, which can guide the paper strip just unwound from the paper roll, and then passes through the limiting ring and is wound around the outside of the cable; at this time, since the axis position of the cable and the paper roll is nearly coaxial, and the paper strip is limited by the limiting ring, as long as the horizontal position of the limiting ring is controlled, the inclination angle of the paper strip at the upper end of the limiting ring can be controlled, so as to adjust the angle between the paper strip and the wrapping part of the vertical part of the cable, and then adjust the paper strip wrapping efficiency and the wrapping coverage rate of the paper strip; and when the angle is smaller, the wrapping efficiency is faster and the wrapping coverage rate is smaller.

[0009] Preferably, a screw rod is horizontally fixed on the outer side of the fastener, an adjusting nut is fixed on one end of the limiting ring close to the fastener, and the adjusting nut is threadedly connected to the screw rod.

[0010] By adopting the above technical solution, when it is necessary to control the sliding position of the limit ring, the adjusting nut can be rotated to achieve the movement adjustment of the limit ring in the horizontal direction.

[0011] Preferably, a locking nut is threadedly connected to the screw rod, and the locking nut is pressed against one side of the adjusting nut.

[0012] By adopting the above technical solution, after adjusting the position of the limiting ring, the locking nut can be rotated so that the locking nut abuts against one side of the adjusting nut, thereby reducing the loosening of the adjusting nut and ensuring the position stability of the limiting ring.

[0013] Preferably, the limiting ring is provided with a notch near the position where the locking nut abuts.

[0014] By adopting the above technical solution, a notch is set to facilitate the paper strip to enter and exit the limiting ring. When the limiting ring is rotated to adjust the position, the paper strip can be moved out of the limiting ring from the notch, so that the limiting ring will not affect the paper strip during adjustment.

[0015] Preferably, the fastener includes a threaded sleeve, a rotating cylinder and a clamping bolt, the inner wall of the threaded sleeve is provided with a threaded portion, the threaded sleeve is threadedly connected to the first sleeve, the rotating cylinder is sleeved on the outside of the threaded sleeve, the clamping bolt is threadedly connected to the outside of the rotating cylinder and abuts against the outside of the threaded sleeve, and the screw is provided on the outside of the rotating cylinder.

[0016] By adopting the above technical solution, when the rotating drum is rotated to the required position, the clamping bolt is used to tighten the rotating drum and the threaded sleeve so that the rotating drum and the threaded sleeve are relatively fixed, and the circumferential position of the limit ring at the first sleeve can be adjusted to improve the applicability; and when the threaded sleeve is rotated to press the paper roll, the clamping bolt can be loosened to prevent the limit ring and the rotating drum from rotating with the threaded sleeve.

[0017] Preferably, the outer side surface of the threaded sleeve is provided with a convex edge, the convex edge is arranged around the outer side of the threaded sleeve, and the lower end of the rotating cylinder overlaps the upper surface of the convex edge.

[0018] By adopting the above technical solution, when the rotating drum is sleeved on the outside of the threaded sleeve, the convex edge can support the rotating drum, thereby improving the installation stability of the rotating drum.

[0019] Preferably, at least two clamping bolts are evenly arranged in the circumferential direction of the drum.

[0020] By adopting the above technical solution, the rotating drum can be tightened from at least two positions, further improving the stability of the rotating drum when it is fixed.

[0021] Preferably, the guide rod includes a vertical portion and an inclined portion, the lower end of the vertical portion is fixed to the supporting plate, the lower end of the inclined portion is connected to the upper end of the vertical portion, and the inclined portion is inclined upward and away from the first sleeve.

[0022] By adopting the above technical solution, when the paper strip bypasses the vertical portion, the inclined portion can limit the paper strip from sliding upward, thereby reducing the chance of the paper strip escaping from the guide rod.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] (1) By setting the cooperation between the fastener and the limit ring, it is convenient to adjust the angle between the paper strip and the vertical part of the cable, thereby adjusting the wrapping efficiency and the wrapping coverage of the paper strip;

[0025] (2) By providing a notch, it is easier for the paper strip to enter and exit the limiting ring, reducing the entanglement of the paper strip when the limiting ring position is adjusted;

[0026] (3) The fastener includes a threaded sleeve, a rotating drum and a locking bolt, which is convenient for controlling the position of the limit ring in the circumferential direction of the first sleeve. When the threaded sleeve rotates to compress the paper roll, the locking bolt can be loosened to prevent the rotating drum and the locking bolt from rotating synchronously.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a paper wrapping machine. Figure 1 and Figure 2 The paper wrapping machine includes a frame 1, a carrying plate 2, a guide rod 3, a first sleeve 4 and a second sleeve 5.

[0033] The carrier plate 2 is in the shape of a round block and is arranged horizontally. The carrier plate 2 is rotatably connected to the frame 1. The rotation axis of the carrier plate 2 is located on its own axis. A driving motor for driving the carrier plate 2 to rotate is installed on the frame 1. The first sleeve 4 and the second sleeve 5 are both hollow tubular structures. The first sleeve 4 is fixed to the upper surface of the carrier plate 2 and is located at the axis position of the carrier plate 2. When the carrier plate 2 rotates, the first sleeve 4 rotates synchronously. The second sleeve 5 is fixed to the frame 1 and is located directly above the first sleeve 4. The first sleeve 4 and the second sleeve 5 are located in the same vertical direction. The cable passes vertically through the first sleeve 4 and the second sleeve 5 for transportation. The part where the cable contacts and wraps the paper strip is located between the first sleeve 4 and the second sleeve 5.

[0034] The reel of the paper roll is sleeved on the first sleeve 4, and one side of the paper roll is attached to the upper surface of the carrier plate 2. A fastener 6 for clamping and fixing the paper roll is provided on the first sleeve 4, so that the paper roll is fixed to the carrier plate 2. Specifically, the fastener 6 includes a threaded sleeve 61, the outer side of the first sleeve 4 is processed with an external thread, and the inner wall of the threaded sleeve 61 is processed with a threaded portion that matches the external thread, so that the paper roll can be clamped by the threaded sleeve 61 by rotating the threaded sleeve 61.

[0035] The guide rod 3 is fixed to a position near the edge of the upper surface of the carrier plate 2. The guide rod 3 includes a vertical portion 31 and an inclined portion 32 connected in an integral manner. The lower end of the vertical portion 31 is fixed to the carrier plate 2, and the lower end of the inclined portion 32 is obliquely fixed to the upper end of the vertical portion 31. The inclined portion 32 is inclined upward and away from the first sleeve 4. When the paper roll unwinds the paper strip, the paper strip bypasses the vertical portion 31 and then winds upward outside the cable. The inclined portion 32 can prevent the paper strip from escaping from the guide rod 3.

[0036] A limit ring 7 is movably connected to the fastener 6. Specifically, the limit ring 7 is slidably adjusted along the horizontal direction; after the paper strip is wound around the outside of the guide rod 3, it passes through the limit ring 7 and is then wound around the outside of the cable. In this embodiment, the movable adjustment range of the limit ring 7 is located between the guide rod 3 and the first sleeve 4. Since the cable is limited by the limit ring 7, the bending position of the paper strip is also changed by adjusting the horizontal position of the limit ring 7. That is, the inclination angle of the paper strip at the upper end of the limit ring 7 can be adjusted to adjust the angle between the paper strip and the wrapping part of the vertical part 31 of the cable. When the angle is smaller, the wrapping efficiency is faster and the wrapping coverage is smaller, thereby adjusting the wrapping efficiency and the wrapping coverage of the paper strip.

[0037] Among them, refer to Figure 2 and Figure 3 A screw rod 8 is horizontally fixed on the outside of the fastener 6, and an adjusting nut 9 is fixed on one end of the limiting ring 7 close to the fastener 6, and the adjusting nut 9 is threadedly connected to the screw rod 8; when the adjusting nut 9 is rotated, the horizontal activity adjustment of the limiting ring 7 can be realized.

[0038] In some embodiments, a locking nut 10 is threadedly connected to the screw rod 8, and the locking nut 10 is pressed against one side of the adjusting nut 9; after the position of the limiting ring 7 is adjusted, the locking nut 10 is rotated so that one side of the locking nut 10 is pressed against one side of the adjusting nut 9, thereby improving the stability of the limiting ring 7 after adjustment.

[0039] In some embodiments, the limiting ring 7 is a square frame, and a notch 11 is provided at a position of the limiting ring 7 near the fastening nut 10. The notch 11 facilitates the paper strip to enter and exit the limiting ring 7 horizontally, and when the limiting ring 7 is rotated to adjust the position, the paper strip can be moved out of the limiting ring 7 from the notch 11, so that the limiting ring 7 will not affect the paper strip during adjustment, and it is also convenient for the paper strip to re-enter the limiting ring 7 horizontally.

[0040] In some embodiments, the fastener 6 further includes a rotating cylinder 62 and a clamping bolt 63. The rotating cylinder 62 is sleeved on the outside of the threaded sleeve 61. The screw 8 is horizontally fixed on the outside of the rotating cylinder 62. The clamping bolt 63 is horizontally threadedly connected to the rotating cylinder 62. The clamping bolt 63 passes through the rotating cylinder 62 and abuts against the outside of the first sleeve 4 of the rotating cylinder 62. When the rotating cylinder 62 is rotated to a desired position, the clamping bolt 63 is tightened, and the rotating cylinder 62 and the first sleeve 4 are relatively fixed. When the clamping bolt 63 is loosened, the rotating cylinder 62 and the threaded sleeve 61 can rotate relative to each other, so that the circumferential position of the limit ring 7 located on the first sleeve 4 can be adjusted, thereby improving applicability.

[0041] At least two clamping bolts 63 are evenly arranged in the circumferential direction around the rotating drum 62. In this embodiment, two clamping bolts 63 are selected. The clamping bolts 63 can tighten the rotating drum 62 from at least two positions, further improving the stability of the rotating drum 62 when it is fixed.

[0042] In some embodiments, a flange 12 is fixed to the outer side of the threaded sleeve 61. The flange 12 is arranged around the outer side of the threaded sleeve 61. The lower end of the rotating drum 62 overlaps the upper surface of the flange 12. The flange 12 can support the rotating drum 62 and improve the installation stability of the rotating drum 62.

[0043] A spring 13 is sleeved on the first sleeve 4 and is located between the carrier plate 2 and the convex edge 12. The upper end of the spring 13 abuts against the convex edge 12 and the lower end abuts against the reel of the paper roll; therefore, the paper roll can be elastically tightened by the spring 13 and the loosening of the threaded sleeve 61 is reduced.

[0044] The implementation principle of a paper wrapping machine in the embodiment of the present application is as follows: during operation, after the paper strip is unwound from the paper roll, it first passes through the outside of the guide rod 3, then passes through the limiting ring 7, and finally wraps around the outside of the cable. Since the cable is limited by the limiting ring 7, when the limiting ring 7 is rotated and the horizontal position of the limiting ring 7 is adjusted, the bending position of the paper strip also changes, and when the limiting ring 7 is rotated, the paper strip can move out of the limiting ring 7 from the notch 11. After the position of the limiting ring 7 is adjusted, the paper strip enters the limiting ring 7 from the notch 11. That is, by adjusting the inclination angle of the paper strip at the upper end of the limiting ring 7, the angle between the paper strip and the wrapping part of the vertical part 31 of the cable can be adjusted. When the angle is smaller, the wrapping efficiency is faster and the wrapping coverage rate is smaller, thereby adjusting the wrapping efficiency and the wrapping coverage rate of the paper strip.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
