Description

Technical Field

[0001] The invention belongs to the technical field of cable sheath processing, and in particular relates to a multi-stage cooling treatment device and a working method for cable sheath extrusion. Background Art

[0002] The cable sheath is the outermost layer of the cable, generally made of materials such as polyvinyl chloride. Its main function is to protect the core from erosion by the surrounding environment, and at the same time it can play an insulating role and extend the service life. The cable sheath is extruded by a cable extruder. The cable sheath extruder uses the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then forms it through the die. The surface temperature of the formed material is high and needs to be shaped by a cooling device before it can be processed and used.

[0003] Most traditional cooling treatment devices directly spray water on the newly extruded cable sheath or pass it into a cold water tank for cooling. Then, when the cable sheath is removed from the cold water tank, the water stains remaining on the surface of the cable sheath need to be wiped off through the mounting plate. However, during long-term operation, the mounting plate will become saturated due to absorbing a large amount of water, resulting in poor subsequent water removal effect, which in turn affects the effect of wiping water stains on the cable sheath surface, causing water stains to still remain on the surface of the cable sheath, corroding and accelerating cable aging and affecting the aesthetic performance of the cable sheath. In addition, most of the existing ones do not have a pre-cooling mechanism, and direct water cooling is likely to cause watermarks on the surface of the cable sheath, affecting the quality of the cable sheath.

[0004] Therefore, we propose a multi-stage cooling treatment device and working method for cable sheath extrusion to solve the above problems. Summary of the invention

Moreover, most of the existing ones do not have a pre-cooling mechanism, and direct water cooling is likely to cause watermarks on the surface of the cable sheath, affecting the quality of the cable sheath.

[0012] As a preferred embodiment of the present invention, a second cooling mechanism is arranged above the treatment box, and the second cooling mechanism includes a water tank and a water pump, and the water tank and the water pump are both arranged on the upper surface of the treatment box, the right side of the water pump is connected with the inner bottom of the water tank through a suction pipe, and a water outlet pipe is arranged at the lower end of the water pump, and an annular water spray pipe is arranged at the lower end of the water outlet pipe, and a plurality of atomizing nozzles are arranged in a circular array on the inner circle of the annular water spray pipe, a connecting pipe is arranged at the upper end of the water tank, and the lower left end of the connecting pipe is inserted into the interior of the upper end of the treatment box and connected with the interior of the treatment box, and a condensation plate is arranged on the inner wall of the upper right end of the connecting pipe.

[0013] As a preferred embodiment of the present invention, the rear side of the annular water spray pipe is connected to the rear inner wall of the processing box through a support rod, and the annular water spray pipe is arranged on the right side of the partition and located on the left side of the mounting plate.

[0014] As a preferred embodiment of the present invention, a multi-stage cooling treatment working method for cable sheath extrusion specifically comprises the following steps:

[0015] Step 1: First, let the cable sheath just coming out of the extruder enter the inside of the processing box from the middle of the left side of the processing box, and then move it out from the middle of the right side after passing through the inside of the processing box. When the cable sheath moves into the inside of the fixing seat, start the fan to blow the wind into the spiral air duct through the air inlet and the air inlet duct. When the wind entering the spiral air duct moves to the right, it can carry the heat on the surface of the cable sheath and blow it into the ventilation duct to perform preliminary cooling treatment on the cable sheath.

[0016] Step 2: The cable sheath then passes through the fixing seat and the partition and moves to the annular water spray pipe. The water pump is started, and the water pump draws water from the water tank and sends it into the annular water spray pipe through the water outlet pipe. Then, the atomizing nozzle arranged on the annular water spray pipe sprays water on the circumferential outer surface of the cable sheath in the form of water mist, so that the water mist evaporates quickly to take away the heat, and then further cools the cable sheath.

[0017] Step 3, after that, when the cable sheath continues to move to the right and contacts with the dewatering sponge on the mounting plate, the dewatering sponge can wipe off excess water sprayed on the surface of the cable sheath to prevent water stains from remaining on the cable sheath and corroding the aged cable sheath. After the dewatering sponge has been dewatering the cable sheath for a period of time, the stepper motor is started, and the stepper motor drives the worm to rotate, so that the worm drives the worm wheel, the rotating shaft and the rotating gear to rotate, and then the rotating gear drives the gear ring and the turntable to rotate. After the turntable rotates half a circle, the hinged rods on the left and right sides can respectively drive the mounting plates and the dewatering sponge on the left and right sides to move vertically, and then the mounting plate and the dewatering sponge on the left side move downward to fit with the corresponding squeezing plates, and perform a squeezing operation to squeeze out the water in the dewatering sponge, and the mounting plate and the dewatering sponge on the right side move upward to contact with the outer surface of the cable sheath, and the cable sheath is dewatered, so that the left and right groups of dewatering sponges are replaced alternately, so as to prevent one group of dewatering sponges from being used all the time, resulting in saturation of the dewatering sponge and affecting the dewatering effect;

[0018] Step 4. When the cable sheath continues to move to the right to the inside of the annular air jet pipe, the air compressor starts to work, compresses the wind inside the ventilation pipe and discharges it into the inside of the air outlet pipe 1 and the air outlet pipe 2. Then the wind inside the air outlet pipe 1 is sprayed on the outer surface of the cable sheath through the annular air jet pipe to dry the cable sheath, further improving the water removal effect. The wind discharged from the air outlet at the air outlet of the air outlet pipe 2 causes an upward airflow to be generated inside the treatment box. The airflow drives the water vapor generated during cooling to flow into the inside of the connecting pipe. Then the water vapor condenses into water droplets at the condensation plate and falls into the inside of the water tank, so that the water can be recycled. The air-dried cable sheath is moved out from the right end of the treatment box to complete the cooling work.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) Through the provided driving mechanism and wiping mechanism, after the water stains on the surface of the cable sheath are wiped by the water-removing sponge for a period of time, the driving mechanism works, so that the installation plates and water-removing sponges of the left and right groups move vertically once, and then the positions of the installation plates and water-removing sponges of the left and right groups are exchanged, so that the water-removing sponges that have absorbed a large amount of water move downward to contact with the squeezing plate to squeeze water, and the dry water-removing sponges move to contact with the outer surface of the cable sheath to continue the water removal work, so that the water removal effect is always in a high-efficiency state, avoiding the residual water stains on the surface of the cable sheath affecting the quality of the cable sheath;

[0021] (2) The cooling mechanism 1 is provided to air-cool the newly extruded cable sheath, thereby avoiding water marks on the surface of the cable sheath when the cable sheath is directly water-cooled, thereby improving the quality of the finished product of the cable sheath;

[0022] (3) By setting up the cooling mechanism 2, water can be sprayed on the surface of the cable sheath in the form of water mist, thereby improving the cooling efficiency of the cable sheath. By setting up the air-drying mechanism, the water stains on the surface of the cable sheath can be further dried by air. At the same time, the water vapor in the treatment box can be blown into the water tank, so that the water can be recycled and the waste of resources can be reduced. At the same time, it can prevent the water vapor from condensing again inside the treatment box and dripping on the surface of the cable sheath, thereby affecting the cooling and water removal effect.

Four fixed plates 608 are provided, and two are provided on the inner wall of the rear side of the processing box 1, and two are provided on the inner wall of the front end of the processing box 1. A turntable 602 is rotatably installed inside the fixed plate 1 601, and two turntables 602 are provided. The circumferential surfaces on the right sides of the two turntables 602 are provided with toothed rings 603.

The annular water spray pipe 404 is provided on the right side of the partition 2 and located on the left side of the mounting plate 605.

[0038] It should be noted that the left and right hinged rods 604 are connected to the turntable 602 through pins, and are respectively located on the upper and lower sides in opposite positions in the front and rear directions, so that after the turntable 602 rotates half a circle, the left and right hinged rods 604 can respectively drive the left and right mounting plates 605 and dewatering sponges to move vertically, so that the left mounting plate 605 can move downward to the bottom of the cable sheath, and the right mounting plate 605 moves upward to contact the outer surface of the cable sheath, thereby realizing the replacement of the left and right sets of dewatering sponges.

[0039] The four mounting plates 605 are provided with connecting blocks 606 on the side surface away from the water-removing sponge, and the inner sides of the four connecting blocks 606 are rotatably connected with rotating sliders 607, and the rotating sliders 607 are movably installed inside the second fixed plate 608, and the left and right side walls of the two second fixed plates 608 are provided with arc grooves 609, and the four rotating sliders 607 are respectively slidably installed inside the four arc grooves 609, and the right inner bottom of the processing box 1 is provided with a column 8, and the column 8 is provided with two, and the upper ends of the two columns 8 are provided with water squeezing plates 9, and the four mounting plates 605 are respectively arranged on the front and rear sides of the two columns 8;

Similarly, when the connecting block 606 moves downward, the connecting block 606 drives the water-removing sponge to gradually move away from the water squeezing plate 9, and then moves away to the maximum distance in the middle of the arc groove 609. Then, when the connecting block 606 continues to drive the water-removing sponge to move downward, it will gradually approach the water squeezing plate 9, so that the connecting block 606 and the water squeezing plate 9 cooperate with each other to squeeze water out of the water-removing sponge, and squeeze out the water absorbed in the water-removing sponge, so as to facilitate the next alternating replacement of the water-removing sponge.

Example

[0043] Please refer to Figure 1 - Figure 7 As shown, the present invention also discloses a multi-stage cooling treatment method for cable sheath extrusion, which specifically includes the following steps:

[0044] Step 1: First, the cable sheath just coming out of the extruder enters the processing box 1 from the middle of the left side, and moves out from the middle of the right side after passing through the processing box 1. When the cable sheath moves into the fixing seat 301, the fan 303 is started to blow the wind into the spiral air duct 304 through the air inlet 11 and the air inlet duct 302. When the wind entering the spiral air duct 304 moves to the right, it can carry the heat on the surface of the cable sheath and blow it into the ventilation pipe 701 to perform preliminary cooling treatment on the cable sheath.

[0045] Step 2: The cable sheath then passes through the fixing seat 301 and the partition 2 and moves to the annular water spray pipe 404, and the water pump 402 is started. The water pump 402 pumps the water inside the water tank 401 out and sends it into the annular water spray pipe 404 through the water outlet pipe 403. Then, the atomizing nozzle provided on the annular water spray pipe 404 sprays the water in the form of water mist on the circumferential outer surface of the cable sheath, so that the water mist evaporates quickly to take away the heat, and then further cools the cable sheath;

[0046] Step 3: After that, the cable sheath continues to move to the right until it contacts the dewatering sponge on the mounting plate 605. The dewatering sponge can wipe off the excess water sprayed on the surface of the cable sheath to prevent water stains from remaining on the cable sheath and corroding the aged cable sheath. After the dewatering sponge has been dewatering the cable sheath for a period of time, the stepper motor 501 is started. The stepper motor 501 drives the worm 502 to rotate, so that the worm 502 drives the worm wheel 503, the rotating shaft 504 and the rotating gear 505 to rotate, and then the rotating gear 505 drives the gear ring 603 to rotate and the rotating disk 602 to rotate. After rotating half a circle, the left and right mounting plates 605 and the dewatering sponge can be driven to move vertically through the hinged rods 604 on the left and right sides, and then the mounting plate 605 and the dewatering sponge on the left side move downward to fit with the corresponding squeezing plate 9, and perform a squeezing operation to squeeze out the water in the dewatering sponge, and the mounting plate 605 and the dewatering sponge on the right side move upward to contact with the outer surface of the cable sheath to dewater the cable sheath, thereby realizing the alternating replacement of the left and right groups of dewatering sponges, and avoiding the saturation of the dewatering sponge due to the continuous use of one group of dewatering sponges, which affects the dewatering effect;

[0047] Step 4. When the cable sheath continues to move to the right to the inside of the annular air jet pipe 704, the air compressor 702 starts to work, compresses the wind inside the ventilation pipe 701 and discharges it into the inside of the air outlet pipe 1 703 and the air outlet pipe 2 705. Then the wind inside the air outlet pipe 1 703 is sprayed on the outer surface of the cable sheath through the annular air jet pipe 704 to air-dry the cable sheath, further improving the dehydration effect. The wind discharged from the air outlet at the air outlet pipe 2 705 causes an upward airflow to be generated inside the treatment box 1. The airflow drives the water vapor generated during cooling to flow into the inside of the connecting pipe 405. Then the water vapor condenses into water droplets at the condensation plate 14 and falls into the inside of the water tank 401, so that the water can be recycled. The air-dried cable sheath is moved out from the right end of the treatment box 1 to complete the cooling work.

9. A multi-stage cooling process for cable sheath extrusion, characterized in that: The multi-stage cooling treatment device for cable sheath extrusion according to any one of claims 1 to 8 is applied to realize the multi-stage cooling treatment device for cable sheath extrusion, and specifically comprises the following steps: Step 1: First, the cable sheath just coming out of the extruder enters the processing box (1) from the middle of the left side of the processing box (1), and moves out from the middle of the right side after passing through the processing box (1). When the cable sheath moves into the interior of the fixing seat (301), the fan (303) is started to blow air into the spiral air duct (304) through the air inlet (11) and the air inlet duct (302). When the air entering the spiral air duct (304) moves to the right, it can carry the heat on the surface of the cable sheath and blow it into the ventilation duct (701), thereby performing a preliminary cooling treatment on the cable sheath. Step 2: The cable sheath then passes through the fixing seat (301) and the partition (2) and moves to the annular water spray pipe (404), and the water pump (402) is started. The water pump (402) pumps water from the water tank (401) and sends the water to the annular water spray pipe (404) through the water outlet pipe (403). Then, the water is sprayed on the circumferential outer surface of the cable sheath in the form of water mist through the atomizing nozzle provided on the annular water spray pipe (404), so that the water mist evaporates quickly to take away the heat, thereby further cooling the cable sheath. Step 3: After that, the cable sheath continues to move to the right until it contacts the dewatering sponge on the mounting plate (605). The dewatering sponge can wipe off the excess water sprayed on the surface of the cable sheath to prevent water stains from remaining on the cable sheath and corroding the aged cable sheath. After the dewatering sponge has been dewatering the cable sheath for a period of time, the stepper motor (501) is started. The stepper motor (501) drives the worm (502) to rotate, so that the worm (502) drives the worm wheel (503), the rotating shaft (504) and the rotating gear (505) to rotate, and then the rotating gear (505) drives the gear ring (603) to rotate and the turntable (602) to rotate. After the turntable (602) rotates half a circle, the hinged rods (604) on the left and right sides can respectively drive the installation plates (605) and the dewatering sponges on the left and right sides to move in the vertical direction, and then the installation plate (605) and the dewatering sponge on the left side move downward to fit with the corresponding squeezing plate (9) to perform a squeezing operation to squeeze out the water in the dewatering sponge, and the installation plate (605) and the dewatering sponge on the right side move upward to contact with the outer surface of the cable sheath to dewater the cable sheath, thereby realizing the alternating replacement of the left and right groups of dewatering sponges, thereby preventing one group of dewatering sponges from being used all the time, resulting in saturation of the dewatering sponge and affecting the dewatering effect; Step 4: When the cable sheath continues to move to the right to the inside of the annular air jet pipe (704), the air compressor (702) starts to work, compresses the air inside the ventilation pipe (701) and discharges it into the inside of the air outlet pipe 1 (703) and the air outlet pipe 2 (705). Then, the air inside the air outlet pipe 1 (703) is sprayed on the outer surface of the cable sheath through the annular air jet pipe (704), so as to air-dry the cable sheath and further improve the dewatering effect. The air discharged from the air outlet at the air outlet pipe 2 (705) generates an upward airflow inside the treatment box (1). The airflow drives the water vapor generated during cooling to flow into the inside of the connecting pipe (405). Then, the water vapor condenses into water droplets at the condensation plate (14) and falls into the inside of the water tank (401), so that the water can be recycled. The air-dried cable sheath is moved out from the right end of the treatment box (1), completing the cooling work.
