[0002] Polypropylene is a non-toxic and harmless material. The cables made of it will not release toxic and harmful substances during use and will not harm human health. In order to further improve the performance of polypropylene materials, blending modification, grafting modification and other methods are usually used to reduce the modulus and rigidity of the material without losing heat resistance, increase flexibility, and make it more suitable for use with cables. For example, it is prepared as a cable protection tube. The cable protection tube is a pipe or casing specially used to protect the cable from external damage. It can effectively prevent the cable from being damaged by mechanical pressure, chemicals, moisture, corrosion and electromagnetic interference, thereby extending the service life of the cable.

Then the trimming mechanism is provided with a trimming component and a transfer component to cooperate, and the pipeline is driven to synchronously spirally lift through the movement of the lifting seat. The spiral lifting of the pipeline can not only bring a certain self-cleaning effect, but also polish and trim the pipeline from the outside of the pipeline in this process. The trimmer polishes and trims the pipeline from the inside of the pipeline, and the grinding position and angle can be adjusted. Because the pipeline is spirally lifted, the surrounding water flow is disturbed, thereby cleaning the pipeline synchronously, and the intensity of the grinding can be buffered to reduce the damage to the polypropylene composite pipeline. Through the above technical solution, efficient and intelligent production of polypropylene composite materials for cables can be achieved, and the production method is consistent and the operation is simple.

During the movement, the trimming component 304 cooperates with the transfer component 303 to drive the pipe to move up and down while rotating in situ, so as to synchronously trim and clean the inside and outside of the pipe immersed in the trimming liquid.

[0036] like Figure 4-Figure 5 As shown, the cooling and cutting mechanism 2 includes a fixed box 202 located on the trimming mechanism 3, a telescopic box 201 slidably arranged on a box opening at one end of the fixed box 202 and connected to the extrusion head 101, and a movable plate 203 movably arranged on the box opening at the other end of the fixed box 202.

[0037] The telescopic box 201 is driven by a cylinder 1 to slide in and out of a box opening at one end of the fixed box 202. The telescopic box 201 is provided with a discharge through hole for the extruder head 101 to pass through. The telescopic box 201 is also provided with a pipeline external cooling member.

[0038] Notches 204 are provided at the top and bottom of the fixed box 202 opposite to the movable plate 203 to ensure space for the pipeline to turn. At the same time, the notch 204 at the bottom is connected to the feed port of the trimming mechanism 3. A steering member located between the top and bottom notches 204 and a cutting member located between the steering member and the external cooling member of the pipeline are provided on the fixed box 202.

[0039] The movable plate 203 is driven by the cylinder 205 to move horizontally on one side of the steering member, and a cooling member is provided inside the pipeline.

[0040] The steering member includes a rotating disk 213 which is rotatably arranged on the side wall of the fixed box 202 and driven by a motor; two groups of steering rollers 212 are both rotatably arranged on the rotating disk 213, and the spacing between them is adjustable.

[0041] A mounting groove is provided on the rotating disk 213; a lead screw 214 driven to rotate by a second motor is provided in the mounting groove; the driving end of the steering roller 212 is threadedly connected to the lead screw 214 to drive the two groups of steering rollers 212 to move, and the spacing is adjusted to match the outer diameter of the pipeline. At the same time, the roller body of the steering roller 212 is driven to rotate by the driving end to drive the pipeline to move.

[0042] When the pipe moves horizontally to extend between the two sets of steering rollers 212, the two sets of steering rollers 212 approach to clamp the pipe end. When the pipe cutting is completed, the rotating disk 213 rotates 90 degrees to make the pipe turn vertically and extend from the notch 204 at the bottom.

[0043] The external cooling part of the pipeline includes a fan 207 and an air outlet seat 206 connected to the fan 207; the air outlet seat 206 is annular, arranged along the inner wall of the telescopic box 201, and opposite to the extruder head 101, and multiple groups of air outlet heads are arranged along the inner wall.

[0044] After the pipe is extruded, it directly enters the cooling and cutting channel from the discharge hole. When passing through the air outlet seat 206, the air outlet head blows air to the outer wall of the pipe to cool and shape it. After the pipe production is completed, the telescopic box 201 is extended to expose the extrusion head 101 for maintenance and cleaning.

[0045] The cooling part inside the pipeline includes a fan 209 and a telescopic air outlet pipe 208; the air outlet head of the telescopic air outlet pipe 208 supplies air to the inside of the pipeline through the electronically controlled telescopic inlet and outlet of the pipeline, so as to achieve the purpose of cooling and shaping the inside before cutting.

[0046] The cutting pieces are arranged in two groups one above the other, each group comprising a driving box 211 and a cutting knife 210 driven up and down by the driving box 211; after cooling, the pipe can be cut by the relative movement of the cutting knives 210 to obtain a pipe of a desired length.

[0047] like Figure 6 As shown, the trimming mechanism 3 includes a trimming box 301 and a conveyor belt unit 302 arranged in the trimming box 301; multiple groups of transfer components 303 are arranged along the conveyor belt of the conveyor belt unit 302 to transfer the pipeline from the feed port to the discharge port; multiple groups of trimming components 304 are arranged along the bottom of the trimming box 301, and cooperate with the transfer components 303 above to trim the pipeline that moves up and down and rotates at the origin.

[0048] It should be further explained that the conveyor belt unit 302 is provided with double layers, which are respectively located on both sides of the transfer component 303. The driving motor drives the rotating shaft to rotate, and the conveyor belt sleeved on the rotating shaft can drive the transfer component 303 to move in a circular motion, back and forth between the feed port and the discharge port.

[0049] It should be further explained that an aeration box 305 is provided in the trimming box 301; the aeration box 305 is located below the discharge port, and air is ventilated by the air pump 306 to form an air flow, which pushes the suspended debris and dirt in the trimming fluid away from the discharge port to assist in cleaning the pipeline and reduce attachments on the pipeline.

[0050] It should be further explained that the dressing fluid in the dressing box 301 is water, which is used for dust reduction and cleaning during grinding and cleaning of pipelines.

[0051] like Figure 7-Figure 8 As shown, the transfer assembly 303 includes a mounting seat 30302 connected to the conveyor belt, a lifting seat 30303 driven to move on the mounting seat 30302 by a cylinder 30301, and a rotating positioning seat 30304 rotatably arranged on the lifting seat 30303.

[0052] It should be further explained that, on the mating ends of the rotating positioning seat 30304 and the trimming assembly 304 , a positioning groove 30306 is provided in the center, and a positioning ring groove 30305 is provided on the periphery.

[0053] The positioning ring groove 30305 is used to engage the pipe opening. At the same time, inflated air bags are provided on the bottom and wall of the groove. The air bags on the wall of the groove are used to contact the pipe opening to increase the firmness of the engagement, and the air bags on the bottom of the groove are used to push the pipe away from the positioning ring groove 30305.

[0054] like Fig. 9 As shown, the trimming assembly 304 includes a base 30401 installed at the bottom of the trimming box 301, outer trimming plates 30403 slidably arranged on both sides of the base 30401, and an inner trimming piece 30402 located in the middle of the base 30401; the inner trimming piece 30402 includes a support column 30404 installed on the base 30401, a limiting base 30405 installed on the support column 30404, an inner trimmer installed on the outer periphery of the limiting base 30405, and an adjuster installed on the upper end of the limiting base 30405.

[0055] like Fig.10 As shown, the regulator includes an adjusting rod 30406 installed on a limiting base 30405; a threaded adjusting disk 30407 is located at the top of the adjusting rod 30406; an adjusting sleeve 30408 ​​is sleeved on the outside of the adjusting rod 30406, and is threadedly connected to the threaded adjusting disk 30407 to achieve spiral lifting.

[0056] like Fig.10 As shown, a limiting top seat 30409 is provided on the top of the adjusting sleeve 30408; a positioning protrusion 30410 matching the positioning groove 30306 is provided on the limiting top seat 30409; an elastic sealing sleeve 30411 is provided between the bottom of the adjusting sleeve 30408 ​​and the limiting base 30405, and the elastic sealing sleeve 30411 covers the adjusting rod 30406 and pushes the limiting top seat 30409 to the highest position.

[0057] It should be further explained that the positioning protrusion 30410 and the positioning groove 30306 are both cross structures.

[0058] When the transfer assembly 303 moves the pipe to the top of the trimming assembly 304, the positioning protrusion 30410 and the positioning groove 30306 are opposite to each other, and the lifting seat 30303 descends. The limit top seat 30409 extends into the pipe until it engages with the positioning groove 30306. The lifting seat 30303 continues to be lifted and lowered. Since the adjustment sleeve 30408 ​​is threadedly connected with the threaded adjustment disk 30407, the pipe is driven to start spiral lifting. In this process, the outer trimming plate 30403 and the inner trimmer begin to cooperate to trim the pipe.

[0059] like Fig.10 As shown, the trimmer includes a driving box 30412 arranged on a limiting base 30405, a double-headed bidirectional cylinder 30413 rotatably arranged on the driving box 30412, a bending rod 30414 connected to the telescopic rod of the double-headed bidirectional cylinder 30413, and a rotating grinding head 30415 located at the end of the bending rod 30414.

[0060] By driving the motor gear structure in the driving box 30412, the cylinder body of the double-headed bidirectional cylinder 30413 can be driven to rotate, and then the bending rod 30414 can be moved to adjust the grinding position of the rotating grinding head 30415 to match the inner wall of the pipe.

[0061] like Fig.11 As shown, the outer finishing plate 30403 is detachably connected to the movable seat 30416; a guide groove for the sliding of the movable seat 30416 is set on the base 30401; a double-headed bidirectional cylinder 30419 is set in the guide groove to drive the movable seats 30416 on both sides to move synchronously to adjust the spacing of the outer finishing plate 30403 so that it can grind and trim the pipeline from the outside of the pipeline.

[0062] It should be further explained that the guide groove is covered with a telescopic layer 30420; the telescopic layer 30420 moves and telescopes along with the moving seat 30416 to reduce the amount of foreign matter that enters the guide groove.

[0063] It should be further explained that a mounting head is arranged at the bottom of the outer finishing plate 30403, and a finishing surface with a groove is arranged on the side; a mounting hole 30417 for installing the mounting head is arranged at the upper end of the movable seat 30416, and a positioning hole 30418 connected to the mounting hole 30417 is arranged on the side; the mounting head is fixed by screwing the positioning screw into the positioning hole 30418.

[0064] like Figure 12-13 As shown, the discharge mechanism 4 includes a discharge box 401; a receiving port 402 communicating with the discharge port of the trimming box 301 is provided on the side wall of the discharge box 401, and a discharge door 403 is provided on both sides of the receiving port 402. A water filter 404 is provided in the discharge box 401 and below the receiving port 402 and the discharge door 403.

[0065] It should be further explained that the water filter 404 is a trapezoidal structure and is configured as a heatable filter.

[0066] When the pipeline enters the discharge box 401, it can roll down to both sides along the top of the trapezoidal structure. The rolling process accelerates the drying of water, and then the drying of the pipeline is accelerated by heating and filtering water.

[0074] S7. The moving seats 30416 on both sides move synchronously to adjust the spacing of the outer trimming plates 30403, so that the outer trimming plates 30403 can grind and trim the pipe from the outside of the pipe; the grinding position of the rotating grinding head 30415 is adjusted by moving and rotating the bending rod 30414 to match the inner wall of the pipe, so that the pipe can be grinded and trimmed from the inside of the pipe; during the grinding and trimming process, the water flow is stirred, and the cleaning of the pipe is completed synchronously;
