Description

Technical Field

[0001] This utility model belongs to the field of halogen-free flame-retardant cable processing technology, and in particular relates to an auxiliary cooling device for the production of halogen-free flame-retardant cables. Background Technology

[0002] Halogen-free flame-retardant cables are electrical wires and cables that exhibit low smoke, zero halogen release, and flame-retardant properties when burning. Made with halogen-free materials, they eliminate the generation of toxic hydrogen halide gases at the source, producing minimal smoke during combustion and effectively improving visibility in fire situations. Furthermore, the addition of special flame retardants forms a dense carbonized barrier layer that isolates oxygen from flammable materials, making it difficult for flames to persist and significantly reducing the risk of fire spread.

[0003] The problem with the above technology is that water cooling is a common cooling method for halogen-free flame-retardant cables in the existing technology. However, the surface water will become hot due to the heat transfer of the halogen-free flame-retardant cable itself when it is first processed, while the bottom water remains cold, which reduces the cooling efficiency of the halogen-free flame-retardant cable. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a cooling device for halogen-free flame-retardant cables that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: an auxiliary cooling device for the production of halogen-free flame-retardant cables includes a water tank, a first anti-scratching roller, and a second anti-scratching roller. The first anti-scratching roller is disposed on one side of the water tank, and the second anti-scratching roller is rotatably connected to the inner wall of the water tank via a rotating shaft. A connecting plate is fixedly connected to one side of the water tank, and one side of the connecting plate is rotatably connected to the first anti-scratching roller via a rotating shaft. Both the first and second anti-scratching rollers are slightly higher than the top of the water tank. An agitation mechanism and a support frame are disposed above the water tank, and a cleaning mechanism is disposed inside the water tank. The front and rear sides of the water tank are fixedly connected to the inner side of the support frame.

[0006] To circulate the water in the tank and ensure that all water is cold, the agitation mechanism preferably includes a motor, a reciprocating lead screw, a connecting rod, an agitator plate, a slide bar, and a slider. The top of the motor is fixedly connected to a support frame, and the output end of the motor at its bottom is fixedly connected to the reciprocating lead screw. The reciprocating lead screw passes through the slider and extends downwards, with its surface slidably connected to the inner wall of the slider. One end of the slide bar passes through the slider and extends into a threaded groove on the surface of the reciprocating lead screw, where it is slidably connected to the lead screw. The surface of the slide bar is fixedly connected to the inner wall of the slider, and the end of the slide bar that contacts the reciprocating lead screw is hemispherical. One side of the slider is fixedly connected to the connecting rod, and the bottom of the connecting rod extends into the interior of the tank and is fixedly connected to the agitator plate. By starting the motor, the motor drives the reciprocating lead screw to rotate, which in turn drives the slide bar to move up and down. The slide bar drives the slider to move synchronously, and the slider, through the connecting rod, drives the agitator plate to move synchronously. This causes the agitator plate to move in the water, agitating the water and bringing the bottom layer of water to the top, ensuring that all water is cold and improving cooling efficiency.

[0007] To clean the surface of the halogen-free flame-retardant cable, the cleaning mechanism preferably includes a horizontal plate, a fixing sleeve, and a sponge ring. One end of the horizontal plate is fixedly connected to the inner wall of the water tank, the fixing sleeve is fixedly connected to the bottom of the horizontal plate, and the sponge ring is fixedly connected to the inner side of the fixing sleeve. Considering that impurities may adhere to the surface of the halogen-free flame-retardant cable during production, failure to clean these impurities will affect subsequent processing and the quality of the halogen-free flame-retardant cable. After connecting the halogen-free flame-retardant cable to an external traction source, the traction source will pull the halogen-free flame-retardant cable to move. During the movement, the sponge ring contacts and cleans the surface of the halogen-free flame-retardant cable, while the water stirred by the agitator plate also plays an auxiliary cleaning role.

[0008] In order to orderly separate the halogen-free flame-retardant cables and prevent them from rubbing against each other, preferably, the top of the water tank is rotatably connected to a separating roller via a rotating shaft. The separating roller is designed to orderly separate the halogen-free flame-retardant cables and prevent them from rubbing against each other. The separating roller is rotating, which also effectively avoids friction between the halogen-free flame-retardant cables and the separating roller.

[0009] In order to make the halogen-free flame-retardant cable sink below the water surface, preferably, the inner wall of the water tank is rotatably connected to a pressure roller via a rotating shaft. The halogen-free flame-retardant cable is passed through the bottom of the pressure roller and thus restrained underwater by the pressure roller.

[0010] To ensure stable movement of the agitator plate, preferably, a limiting groove is provided on the inner wall of the water tank, and a limiting plate is slidably connected to the inner wall of the limiting groove. One end of the limiting plate is fixedly connected to the agitator plate. The limiting groove and the limiting plate ensure stable movement of the agitator plate.

[0011] In order to collect the impurities cleaned from the surface of the halogen-free flame-retardant cable, preferably, a filter plate is fixedly connected to the inner wall of the water tank, and a water outlet is fixedly connected to the bottom of the water tank. After the water is discharged through the water outlet, the impurities will be blocked on the top of the filter plate, which will facilitate subsequent cleaning.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention solves the problem of existing cooling methods for halogen-free flame-retardant cables, which commonly use water cooling. However, the surface water becomes hot due to the heat transfer from the newly manufactured cable, while the bottom water remains cold, thus reducing the cooling efficiency of the halogen-free flame-retardant cable. This is achieved by setting up an agitation mechanism, which is driven by a motor to rotate a reciprocating screw. The reciprocating screw drives a slide rod to move up and down, and the slide rod drives a slider to move synchronously. The slider, through a connecting rod, drives an agitation plate to move synchronously, causing the agitation plate to move in the water and agitate the water. Attached Figure Description

[0017] like Figures 1 to 4As shown in the figure, an auxiliary cooling device for the production of halogen-free flame-retardant cables provided by this utility model includes a water tank 1, a first anti-scratching roller 3 and a second anti-scratching roller 5. The first anti-scratching roller 3 is disposed on one side of the water tank 1, and the second anti-scratching roller 5 is rotatably connected to the inner wall of the water tank 1 via a rotating shaft. A connecting plate 2 is fixedly connected to one side of the water tank 1, and one side of the connecting plate 2 is rotatably connected to the first anti-scratching roller 3 via a rotating shaft. Both the first anti-scratching roller 3 and the second anti-scratching roller 5 are slightly higher than the top of the water tank 1. An agitation mechanism 7 and a support frame 9 are disposed above the water tank 1. A cleaning mechanism 8 is disposed inside the water tank 1, and both the front and rear sides of the water tank 1 are fixedly connected to the inner side of the support frame 9.

[0018] To activate the water in water tank 1 and ensure that all water is cold, the agitation mechanism 7 includes a motor 701, a reciprocating lead screw 702, a connecting rod 703, an agitator 704, a slide rod 705, and a slider 706. The top of the motor 701 is fixedly connected to the support frame 9, and the output end of the motor 701 is fixedly connected to the reciprocating lead screw 702. The reciprocating lead screw 702 passes through the slider 706 and extends downwards. The surface of the reciprocating lead screw 702 is slidably connected to the inner wall of the slider 706. One end of the slide rod 705 passes through the slider 706 and extends into a threaded groove on the surface of the reciprocating lead screw 702, where it is slidably connected to the reciprocating lead screw 702. The surface of the slide rod 705 is fixedly connected to the inner wall of the slider 706. The connection is as follows: the end of the slide rod 705 that contacts the reciprocating lead screw 702 is hemispherical; one side of the slider 706 is fixedly connected to the connecting rod 703; the bottom of the connecting rod 703 extends into the interior of the water tank 1 and is fixedly connected to the agitator plate 704; by starting the motor 701, the motor 701 drives the reciprocating lead screw 702 to rotate; the reciprocating lead screw 702 drives the slide rod 705 to move up and down; the slide rod 705 drives the slider 706 to move synchronously; the slider 706 drives the agitator plate 704 to move synchronously through the connecting rod 703; the agitator plate 704 moves in the water to agitate the water, bringing the bottom water to the top, making all the water cold and improving the cooling efficiency.

[0019] To clean the surface of the halogen-free flame-retardant cable, the cleaning mechanism 8 includes a horizontal plate 801, a fixing sleeve 802, and a sponge ring 803. One end of the horizontal plate 801 is fixedly connected to the inner wall of the water tank 1, the fixing sleeve 802 is fixedly connected to the bottom of the horizontal plate 801, and the sponge ring 803 is fixedly connected to the inner side of the fixing sleeve 802. Considering that impurities may be attached to the surface of the halogen-free flame-retardant cable during production, if the impurities are not cleaned, it will affect the subsequent processing and the quality of the halogen-free flame-retardant cable. After connecting the halogen-free flame-retardant cable to an external traction source, the traction source will pull the halogen-free flame-retardant cable to move. During the movement, the sponge ring 803 contacts and cleans the surface of the halogen-free flame-retardant cable, while the water stirred by the stirring plate 704 can also play an auxiliary cleaning role.

[0020] In order to orderly separate the halogen-free flame-retardant cables and prevent them from rubbing against each other, the top of the water tank 1 is connected to a separating roller 4 via a rotating shaft. The separating roller 4 is set to orderly separate the halogen-free flame-retardant cables and prevent them from rubbing against each other. The separating roller 4 is rotating, which also effectively avoids friction between the halogen-free flame-retardant cables and the separating roller 4.

[0021] In order to sink the halogen-free flame-retardant cable below the water surface, the inner wall of the water tank 1 is connected to the pressure roller 6 via a rotating shaft. The halogen-free flame-retardant cable passes through the bottom of the pressure roller 6 and is thus confined underwater by the pressure roller 6.

[0022] In order to make the stirring plate 704 move stably, a limiting groove 12 is provided on the inner wall of the water tank 1. A limiting plate 13 is slidably connected to the inner wall of the limiting groove 12. One end of the limiting plate 13 is fixedly connected to the stirring plate 704. Through the setting of the limiting groove 12 and the limiting plate 13, the stirring plate 704 can move stably.

[0023] In order to collect the impurities cleaned from the surface of the halogen-free flame-retardant cable, a filter plate 11 is fixedly connected to the inner wall of the water tank 1, and a water outlet 10 is fixedly connected to the bottom of the water tank 1. After the water is discharged through the water outlet 10, the impurities will be blocked on the top of the filter plate 11, which will facilitate subsequent cleaning.

[0024] The working principle of this utility model: In use, fill water tank 1 until it covers pressure roller 6. Connect motor 701 to an external controller with a PLC control module. Then, pass one end of the halogen-free flame-retardant cable through the top of the first anti-scratch roller 3 and the second anti-scratch roller 5, the bottom of pressure roller 6, and the inside of the sponge ring 803. Connect the cable to an external traction source, which will slowly move the cable. Starting motor 701 drives reciprocating screw 702 to rotate, which in turn drives slide bar 705 to move up and down. Slide bar 705 drives slider 706 to move synchronously, and slider 706, through connecting rod 703, drives agitator 704 to move synchronously, thus agitating the surface. The plate 704 moves in the water, stirring the water and bringing the bottom water to the top, making all the water cold and improving the cooling efficiency. During the slow movement of the halogen-free flame-retardant cable, the sponge ring 803 contacts and cleans the surface of the halogen-free flame-retardant cable, while the water stirred by the agitator plate 704 also plays an auxiliary cleaning role. The first anti-scratching roller 3 and the second anti-scratching roller 5 are used to prevent the halogen-free flame-retardant cable from rubbing against the edge of the water tank 1 and causing damage. The halogen-free flame-retardant cable is passed through the bottom of the pressure roller 6 and can be restricted underwater by the pressure roller 6. The setting of the limiting groove 12 and the limiting plate 13 can make the movement of the agitator plate 704 stable. After the water is discharged through the outlet 10, the impurities will be blocked on the top of the filter plate 11, which is convenient for subsequent cleaning.
