Description

Technical Field

[0001] This utility model belongs to the technical field of wrapping machines, specifically a wrapping machine for wires and cables. Background Technology

[0002] A wrapping machine is a device specifically used for wrapping insulated core wires such as electric wires, power cables, control cables, and optical cables. It uses a rotating turntable to wrap wrapping tape (such as mica tape, cotton paper tape, aluminum foil, polyester film, etc.) around the core wire. It comes in various forms, including single-layer, double-layer, and triple-layer wrapping.

[0003] Wrapping machines are widely used in the wire and cable manufacturing industry. They can improve production efficiency and ensure product quality, making them an indispensable piece of equipment in wire and cable production. However, while existing wrapping machines can perform the function of wrapping wires and cables, in actual use, there are overlapping parts when the wrapping tape rotates and wraps around the surface of the wires and cables. These overlapping parts of the wrapping tape often lift up, and existing wrapping machines cannot compact these lifting parts, resulting in a reduction in wrapping quality. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a wrapping machine for wires and cables, which has the advantage of compacting the wrapping tape.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wrapping machine for wires and cables, comprising a base plate, a mounting column fixedly installed on the top of the base plate, a fixed box fixedly installed on the top of the mounting column, two fixed boxes, the two fixed boxes being fixedly connected to each other, a round shaft movably sleeved inside the fixed box, a connecting rod movably sleeved on the outer surface of the round shaft, a movable shaft movably sleeved inside the left end of the connecting rod, a sponge wheel fixedly sleeved on the outer surface of the movable shaft, four sponge wheels, the four sponge wheels forming a group of two, the two groups of sponge wheels being perpendicular to each other, a gear located outside the fixed box fixedly sleeved on the outer surface of the round shaft, a fixed plate fixedly installed on the outer surface of the fixed box, a limit block fixedly installed on the right side of the fixed plate, a toothed plate movably sleeved on the outer surface of the limit block, the outer surface of the toothed plate meshing with the outer surface of the gear, a fixed block fixedly connected to the right side of the toothed plate, and a first spring fixedly connected between the fixed blocks.

[0006] As a preferred embodiment of this utility model, a vertical plate is fixedly installed on the rear side of the top of the base plate, a cylinder is movably sleeved inside the vertical plate, a disc is fixedly installed on the front side of the cylinder, and a driven roller is fixedly installed on the back side of the cylinder.

[0007] As a preferred embodiment of this utility model, a motor is fixedly installed on the left side of the back of the vertical plate, and a rotating shaft is fixedly connected to the other end of the motor output shaft. A drive roller is fixedly sleeved on the outer surface of the rotating shaft, and the drive roller is connected to the driven roller through a transmission belt.

[0008] As a preferred embodiment of this utility model, an installation rod is fixedly installed on the left side of the front of the disc, a wrapping disc is movably sleeved on the outer surface of the installation rod, and a slot is formed inside the installation rod.

[0009] As a preferred embodiment of this utility model, the outer surface of the mounting rod is movably fitted with a movable block, and the bottom and top ends of the movable block are both movably fitted with insert blocks. There are two insert blocks, one end of each insert block extends into the inside of the slot and is movably fitted with the inner surface of the slot, and the other end of the insert block is fixedly connected to a horizontal plate.

[0010] As a preferred embodiment of this utility model, a hinge rod is hinged to the left end of the horizontal plate, and a push plate is hinged to the left end of the hinge rod.

[0011] As a preferred embodiment of this utility model, a crossbar is movably sleeved inside the push plate, the right end of the crossbar is fixedly connected to the left side of the movable block, and a second spring is fixedly connected to the right side of the push plate, the right end of the second spring being fixedly connected to the left side of the movable block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a sponge wheel, gear, toothed plate and a first spring, allows the wrapped wire to pass between two sets of sponge wheels, thereby squeezing the sponge wheels outward, causing the connecting rod to drive the round shaft to rotate, which in turn drives the gear to rotate, and the gear to drive the toothed plate to move, causing the two toothed plates to move in opposite directions. At this time, the first spring will be stretched, thereby generating a reverse elastic force under the elastic recovery action, so that the sponge wheel can adhere to the surface of the wire, and compact the overlapping part of the wire wrapping.

[0014] 2. This utility model, by setting a slot, a movable block, an insert block, and a push plate, allows the operator to push the push plate to the right when replacing the tape reel. This causes the push plate to move two horizontal plates in opposite directions via a hinge rod, thereby disengaging the insert block from the slot. This releases the fixing effect on the movable block, allowing the operator to remove the movable block from the outer surface of the mounting rod, thus releasing the restriction on the tape reel and facilitating the replacement and installation of the tape reel.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 8As shown, this utility model provides a wrapping machine for wires and cables, including a base plate 1, a mounting column 2 fixedly installed on the top of the base plate 1, a fixed box 3 fixedly installed on the top of the mounting column 2, two fixed boxes 3, the two fixed boxes 3 are fixedly connected to each other, a round shaft 4 is movably sleeved inside the fixed box 3, a connecting rod 5 is movably sleeved on the outer surface of the round shaft 4, a movable shaft 6 is movably sleeved inside the left end of the connecting rod 5, a sponge wheel 7 is fixedly sleeved on the outer surface of the movable shaft 6, four sponge wheels 7, the four sponge wheels 7 are in groups of two, the two groups of sponge wheels 7 are perpendicular to each other, a gear 8 located outside the fixed box 3 is fixedly sleeved on the outer surface of the round shaft 4, a fixed plate 9 is fixedly installed on the outer surface of the fixed box 3, a limit block 10 is fixedly installed on the right side of the fixed plate 9, a toothed plate 11 is movably sleeved on the outer surface of the limit block 10, the outer surface of the toothed plate 11 meshes with the outer surface of the gear 8, a fixed block 12 is fixedly connected to the right side of the toothed plate 11, and a first spring 13 is fixedly connected between the fixed blocks 12.

[0026] By setting two sets of sponge wheels 7, and because the two sets of sponge wheels 7 are perpendicular to each other, the outer surface of the wire can be more fully compacted. When the wire is wrapped and passes between the sponge wheels 7, the sponge wheels 7 will compact the wrapping tape wrapped around the surface of the wire, preventing the overlapping parts of the wrapping tape from lifting up. The first spring 13 is in a stretched state, so that the first spring 13 can pull the two toothed plates 11 to move towards each other under the elastic recovery action.

[0027] Among them, a vertical plate 14 is fixedly installed on the rear side of the top of the base plate 1, a cylinder 15 is movably sleeved inside the vertical plate 14, a disc 16 is fixedly installed on the front of the cylinder 15, and a driven roller 17 is fixedly installed on the back of the cylinder 15.

[0028] As a technical optimization of this utility model, the operator can pass the wire that needs to be wrapped through the inside of the driven roller 17, the cylinder 15 and the disc 16. When the driven roller 17 rotates, it will drive the disc 16 to rotate through the cylinder 15.

[0029] Among them, a motor 18 is fixedly installed on the left side of the back of the vertical plate 14, and a rotating shaft 19 is fixedly connected to the other end of the output shaft of the motor 18. A drive roller 20 is fixedly sleeved on the outer surface of the rotating shaft 19, and the drive roller 20 is connected to the driven roller 17 through the transmission belt 21.

[0030] As a technical optimization of this utility model, the operator starts the motor 18, which causes the rotating shaft 19 to drive the active roller 20 to rotate. The active roller 20, through its cooperation with the transmission belt 21, will drive the driven roller 17 to rotate.

[0031] Among them, a mounting rod 22 is fixedly installed on the left side of the front of the disc 16, and a wrapping tape disc 23 is movably sleeved on the outer surface of the mounting rod 22. A slot 24 is opened inside the mounting rod 22.

[0032] As a technical optimization of this utility model, the operator installs the wrapping tape reel 23 with wrapping tape on the outer surface of the mounting rod 22, so that when the disc 16 rotates, the wrapping tape can be wrapped around the surface of the wire.

[0033] Among them, the outer surface of the mounting rod 22 is movably sleeved with a movable block 25, and the bottom and top ends of the movable block 25 are both movably sleeved with insert blocks 26. There are two insert blocks 26. One end of the two insert blocks 26 extends into the inside of the slot 24 and is movably sleeved with the inner surface of the slot 24. The other end of the insert blocks 26 is fixedly connected to a horizontal plate 27.

[0034] As a technical optimization of this utility model, when the insert block 26 is located inside the slot 24, it will fix the movable block 25, thereby enabling the movable block 25 to limit the position of the tape reel 23.

[0035] Among them, the left end of the horizontal plate 27 is hinged to a hinge rod 28, and the left end of the hinge rod 28 is hinged to a push plate 29.

[0036] As a technical optimization of this utility model, the operator pushes the push plate 29 to the right, so that the push plate 29 can drive the two horizontal plates 27 to move in opposite directions through the hinge rod 28, thereby causing the insert block 26 to disengage from the inside of the slot 24.

[0037] The push plate 29 has a horizontal bar 30 movably connected inside it. The right end of the horizontal bar 30 is fixedly connected to the left side of the movable block 25. The right side of the push plate 29 has a second spring 31 fixedly connected to it. The right end of the second spring 31 is fixedly connected to the left side of the movable block 25.

[0038] As a technical optimization of this utility model, when the push plate 29 moves to the right, it will move along the outer surface of the crossbar 30, thereby limiting the push plate 29.

[0039] Working principle and usage process of this utility model:

[0040] When the operator needs to wrap the wire, they first pass the wire sequentially between the driven roller 17, the cylinder 15, the disc 16, and the sponge wheel 7. Then, by starting the motor 18, the rotating shaft 19 drives the driving roller 20 to rotate. The driving roller 20, in conjunction with the transmission belt 21, drives the driven roller 17 to rotate, which in turn drives the disc 16 to rotate via the cylinder 15. As the disc 16 rotates and the wire advances, the wrapping tape inside the wrapping tape reel 23 wraps around the surface of the wire. The wrapped wire will then exit from both ends. As the two sets of sponge wheels 7 pass between each other, the first spring 13 is in a stretched state. Under the elastic recovery action, the first spring 13 will drive the two fixed blocks 12 to move towards each other, thereby causing the toothed plate 11 to drive the gear 8 to rotate. The gear 8 will drive the connecting rod 5 and the movable shaft 6 to rotate towards the wire through the round shaft 4, so that the sponge wheel 7 can fit against the outer surface of the wire and compact the overlapping part of the wire surface wrapping. Since the two sets of sponge wheels 7 are perpendicular to each other, the outer surface of the wire can be compacted more comprehensively.

[0041] When the operator needs to replace the tape reel 23, the push plate 29 can be pushed to the right, causing the push plate 29 to drive the two horizontal plates 27 to move in opposite directions through the hinge rod 28. This causes the horizontal plates 27 to drive the insert block 26 upward and disengage it from the inside of the slot 24, thereby releasing the fixing effect on the movable block 25. At this time, the operator can remove the movable block 25 from the outer surface of the mounting rod 22 and then replace the tape reel 23. Due to the design of the slot 24, the operator can select different slots 24 according to the size of the tape reel 23, thereby installing tape reels 23 of different sizes.
