Description

Technical Field

[0001] The present invention relates to the technical field of material preparation, and in particular to a method for preparing a liquid-cooled high-power charging pile cable. Background Art

[0002] As an important energy transmission tool, cables play an indispensable role in modern society. The insulation performance and conductor conductivity of cables are their key performance indicators, which are directly related to the transmission efficiency, safety and reliability of cables. At present, the commonly used cable insulation materials are polyethylene (PE), cross-linked polyethylene (XLPE), polyvinyl chloride (PVC), etc.

[0003] In the prior art, before the cable materials are extruded to form the cable protective sleeve, the materials need to be mixed and heated, and then extruded to form the product. However, when the cable materials are mixed, they are all completely mixed by stirring. Although the cable materials can be effectively mixed, the staff need to continuously add materials to the mixing box. The long-term manual work is not only time-consuming and labor-intensive, but also affects the work progress. In addition, the cable materials are not pre-processed into small pieces before mixing, so as to make it easier to improve the subsequent heating and mixing. If the large pieces of cable materials are directly stirred and mixed, the large pieces of materials may not be easily dispersed during the mixing process, resulting in uneven distribution of the components of the cable materials, which ultimately affects the performance and quality of the cable.

[0004] In addition, during the existing heating and mixing, the cable materials are easy to stick to the inner wall of the mixing box. If they are not cleaned for a long time, it may affect the subsequent mixing uniformity of the cable materials and may also cause the equipment to be in contact with the cable materials sticky to the inner wall of the mixing box for a long time, causing wear or damage to the equipment, thereby reducing the service life of the equipment and affecting production efficiency. In view of this, we propose a method for preparing a liquid-cooled high-power charging pile cable. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] One of the purposes of the present invention is to provide a production method comprising the following steps:

[0039] Step 1: Determine the required base materials such as polymers and metals, and select corresponding additives such as antioxidants and stabilizers;

[0040] Step 2: Add raw materials into the mixing box 1 according to the proportion, and make the intermittent feeding structure 400 rotate to stir and crush the raw materials for pre-treatment;

[0041] Step 3: The pre-treated raw materials are shaken by the shaking structure 500 and fed into the subsequent heating and mixing, and the inner wall of the mixing box 1 is scraped to remove sticky materials, so that the materials form a melt with fluidity;

[0042] Step 4: Extruding the cable material, and rapidly cooling the formed material through a subsequent cooling device to ensure uniformity of shape;

[0043] Among them, a feed barrel 2 for guiding flow is fixedly connected through the top of the mixing box 1, a discharge port 3 for discharging material is fixedly connected through the outer ring surface of the mixing box 1, an intermittent unloading structure 400 for intermittent unloading is arranged on the top of the inner side wall of the mixing box 1, a shaking structure 500 for shaking and unloading the received material is arranged at the bottom of the mixing box 1, and an air jet structure 600 for blowing air to the material received by the shaking structure 500 is arranged on the inner side wall of the mixing box 1;

[0044] When the cable material is pretreated, the intermittent feeding structure 400 is rotated to intermittently feed the cable material while crushing and stirring the cable material for pretreatment, and the jet structure 600 is driven to always guide the material fed by the intermittent feeding structure 400 while driving the shaking structure 500 to be in a bent state;

[0045] When the cable materials are heated and mixed, when the intermittent unloading structure 400 rotates over the jet structure 600, the shaking structure 500 will release the pressure and generate rotational shaking, so that the material received by the shaking structure 500 can be quickly unloaded while the sticky heating material is wiped off the inner wall of the mixing box 1. The shaking structure 500 rotates and shakes to contact the jet structure 600, and the material on the surface of the shaking structure 500 can also be shaken up and down.

[0046] The present invention takes into account that before the cable materials are extruded to form the cable protective sleeve, the materials need to be mixed and heated, and then extruded to form the product. However, when the cable materials are mixed, they are all completely mixed by stirring. Although the cable materials can be effectively mixed, it is necessary for the staff to continuously add materials to the mixing box 1. The long-term manual work is not only time-consuming and labor-intensive, but also affects the work progress. In addition, before the existing cable materials are mixed, the cable materials are not pre-processed into small pieces, so as to make it easier to improve the subsequent heating and mixing. If the large pieces of cable materials are directly stirred and mixed, the large pieces of materials may not be easily dispersed during the mixing process, resulting in The uneven distribution of the components of the cable material will eventually affect the performance and quality of the cable. Therefore, the intermittent feeding structure 400 is rotated to intermittently feed the cable material while crushing and stirring the cable material for pretreatment, thereby effectively preventing the cable material from being completely crushed during pretreatment, thereby improving the effect of the cable material pretreatment, and driving the jet structure 600 to always maintain the flow of the material under the intermittent feeding structure 400 while driving the shaking structure 500 to be in a bent state, thereby enabling the shaking structure 500 to subsequently better handle the crushed and pretreated cable material and prevent the incompletely crushed material from being crushed again, thereby improving practicality;

[0047] Furthermore, during the existing heating and mixing, the cable material is easy to stick to the inner wall of the mixing box 1. If it is not cleaned for a long time, it may affect the subsequent mixing uniformity of the cable material and may also cause the equipment to contact with the cable material sticking to the inner wall of the mixing box 1 for a long time, causing wear or damage to the equipment, thereby reducing the service life of the equipment and affecting production efficiency. Therefore, when the intermittent feeding structure 400 rotates over the jet structure 600, the shaking structure 500 will release the pressure and produce rotational shaking, so that the material received by the shaking structure 500 can be quickly discharged while wiping off the sticky heating material on the inner wall of the mixing box 1, thereby effectively preventing the cable material from sticking to the mixing box 1 during heating, thereby improving the subsequent heating and mixing effect while reducing the waste of resources, and when the shaking structure 500 rotates and shakes, the jet structure 600 will contact the material on the surface of the shaking structure 500 and can also shake up and down, thereby increasing the feeding speed of the shaking structure 500 for the crushed cable material and improving the cleanliness of the inner wall of the mixing box 1, thereby improving practicality.

[0048] In order to realize the intermittent dropping of the cable material into the mixing box 1, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 7The intermittent material discharging structure 400 includes a rotating shaft 401, which is fixedly connected to the output end of the external motor, and a half gear 402 is fixedly connected to the outer ring surface of the rotating shaft 401, and a full gear 403 for intermittent material discharging is meshedly connected to the outer ring surface of the half gear 402, and a wedge block 404 for driving the jet structure 600 is fixedly connected to the bottom of the full gear 403;

[0049] First, the staff needs to put the cable material into the feed barrel 2, and then use the staff control panel to rotate the rotating shaft 401 fixedly connected to the output end of the external motor to drive the half gear 402 to rotate. At that time, since the teeth on the outer ring surface of the half gear 402 are fully set, when the half gear 402 rotates, it will intermittently drive the full gear 403 to rotate. When the full gear 403 rotates over the feed barrel 2, the full gear 403 will not be connected to the feed barrel 2, so that the cable material intermittently falls into the mixing box 1 for stirring and crushing pretreatment;

[0050] In order to better guide the material dropped by the intermittent feeding structure 400 to the pre-processing position and to center the cable material received by the shaking structure 500, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 6 The jet structure 600 includes a limit plate 603, which is fixedly connected to the inner wall of the mixing box 1. The inner wall of the mixing box 1 is rotatably connected to a circular plate 606, and a wedge rod 601 is slidably connected inside the circular plate 606. The wedge rod 601 and the full gear 403 are adapted to each other. A wave plate 602 for guiding flow is fixedly connected to the top of the limit plate 603, and an outlet pipe 605 for jetting is fixedly connected to the inner annular surface of the circular plate 606;

[0051] When the full gear 403 rotates, it drives the wedge block 404 to rotate around the center of the full gear 403. The rotation of the wedge block 404 will contact and get stuck with the wedge rod 601, driving the wedge rod 601 and the circular plate 606 to slide on the inner wall of the mixing box 1, so that the shaking structure 500 is in a bent state. When the shaking structure 500 is bent to the maximum extent, the circular plate 606 stops rotating, and then the rotating shaft 401 continues to move, which drives the wedge rod 601 to slide inside the circular plate 606, so that The circular plate 606 is inflated and sprayed from the air outlet pipe 605, so that the cable material received by the shaking structure 500 can be blown to the middle of the shaking structure 500, so as to be better filtered to the bottom of the mixing box 1 for heating, stirring and mixing. In addition, since the wave plate 602 is fixedly connected to the surface of the limit plate 603 and the wave plate 602 is wedge-shaped and communicates with the material discharge position of the full gear 403, the material under the full gear 403 can be guided to the surface of the shaking structure 500, thereby improving the subsequent filtering effect of the shaking structure 500;

[0052] In order to achieve the shaking structure 500 to remove the cable material stuck on the inner wall of the mixing box 1 and heat and mix the cable material at the same time, it is necessary to disclose the following specific structure in detail, please refer to Figures 1 to 9 The shaking structure 500 includes a filter plate 501, which is fixedly connected to the inner wall of the circular plate 606. The side of the filter plate 501 is fixedly connected to an elastic rod 502, which is flexibly arranged. The bottom of the circular plate 606 is fixedly connected to a scraping knife 503 for removing the cable material stuck to the inner wall of the mixing box 1.

[0053] When the intermittent feeding structure 400 performs crushing pretreatment on the cable material, the smaller cable material will fall from the holes opened on the surface of the filter plate 501 to the bottom of the mixing box 1. At that time, since a heating wire is arranged inside the bottom of the mixing box 1, after the smaller cable material falls to the bottom of the mixing box 1, the staff manually controls the control panel to heat the bottom of the mixing box 1, and then the rotation of the rotating shaft 401 will drive the stirring blade to make the heated and mixed cable material into a watery state. Moreover, when the inner wall of the mixing box 1 is adhered to the cable material, the above-mentioned circular plate 606 will drive the filter plate 501 and the elastic rod 502 to be bent when rotating. The specific state diagram is as follows: Fig. 9 Therefore, when the wedge block 404 is not in contact with the wedge rod 601, the circular plate 606 will automatically return to the initial position, and drive the filter plate 501, the elastic rod 502 and the scraping knife 503 to return to the original position and rotate and shake, so that the crushed cable materials on the surface of the filter plate 501 can be quickly shaken off to the bottom of the mixing box 1, and the scraping knife 503 can be driven to remove the sticky cable materials from the inner wall of the mixing box 1. When the cable materials at the bottom of the mixing box 1 are in a watery state, the staff will open the discharge port 3 through the control panel to complete the rapid discharge and collection of the mixed cable materials, thereby improving practicality;

[0054] In order to better realize the intermittent unloading of the newly entered cable material, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 7 Two groups of full gears 403 are symmetrically arranged along the center of the rotating shaft 401. The shape of the full gear 403 is larger than the half gear 402. Four groups of wedge blocks 404 fixedly connected to the bottom of the full gear 403 are arranged along the center of the full gear 403. A discharge port communicating with the feed barrel 2 is opened on the surface of the full gear 403.

[0055] At that time, because the shape of the full gear 403 is larger than the half gear 402, the full gear 403 can only be driven to rotate one circle when the half gear 402 rotates many circles. Therefore, when the full gear 403 rotates, the discharge port opened on the surface will not be connected with the feed barrel 2, so that the intermittent discharge of the feed barrel 2 can be completed, preventing the subsequent pretreatment of the cable material from not having enough time, thereby reducing the pretreatment effect;

[0056] In order to better guide the cable material dropped by the full gear 403, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 7 The top of the wave plate 602 is set as an inclined surface, the bottom of the wave plate 602 is set in a wave shape, the bottom of the wave plate 602 is in contact with the wave block 604, and the wave block 604 is fixedly connected and placed in the slide groove opened on the surface of the filter plate 501;

[0057] When the full gear 403 drops the cable material, the wave plate 602 is arranged at the bottom of the full gear 403, so the wave plate 602 can better guide the cable material dropped by the full gear 403 to the surface of the filter plate 501, so as to facilitate the subsequent stirring and crushing of the cable material to pre-treat the cable material, and prevent the cable material just dropped by the full gear 403 from directly entering the bottom of the mixing box 1;

[0058] In order to better realize the centering of the cable material received on the surface of the filter plate 501 and facilitate the pre-processing of the cable material, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 7 , the inner side walls of the circular plate 606 are respectively provided with a plurality of groups of air outlet pipes 605, the inside of the circular plate 606 is slidably connected with the wedge-shaped rod 601, the surface of the circular plate 606 is slidably arranged with the limiting plate 603, and the limiting plate 603 is arc-shaped and fixed to the inner side wall of the mixing box 1;

[0059] When the wedge block 404 rotates to the maximum distance, the wedge rod 601 and the circular plate 606 are also at the maximum rotation distance. Therefore, when the wedge block 404 continues to rotate, it will drive the wedge rod 601 to slide inside the circular plate 606, so that the gas outlet pipe 605 sprays gas to blow the cable materials accumulated on the surface of the filter plate 501 to the middle of the filter plate 501, which is convenient for the subsequent pre-treatment and crushing of the cable materials, and can also make the pre-treated cable materials move, so that they can fall from the holes opened on the surface of the filter plate 501 to the bottom of the mixing box 1.

[0060] In order to better realize the pre-processed and crushed cable materials falling to the bottom of the mixing box 1, it is necessary to disclose the following specific structure in detail, please refer to Figures 1 to 7 , the filter plate 501 has a plurality of holes on its surface, and four groups of elastic rods 502 fixedly connected to the side of the filter plate 501 are respectively arranged along the center of the rotating shaft 401, and the elastic rods 502 are made of flexible material. The position where the filter plate 501 and the elastic rods 502 are fixedly connected is in a closed setting, and the filter plate 501 has a sliding groove on its surface that is adapted to the wave plate 602;

[0061] After the intermittent feeding structure 400 pre-treats the cable material, the holes on the surface of the filter plate 501 allow the pre-treated cable material to quickly fall into the mixing box 1, and the filter plate 501 and the elastic rod 502 can also be dropped when they are in a complete state, and the elastic rod 502 can be bent while being sufficient to bear the weight of the entire cable material, so as to prevent the elastic rod 502 from being too soft and causing the cable material to bend the elastic rod 502 up and down, thereby improving the filter plate 501 to quickly drop the cable material to the bottom of the mixing box 1, thereby improving practicality;

[0062] In order to better remove the sticky cable material from the inner wall of the mixing box 1, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 7 , both sides of the scraping blade 503 are wedge-shaped, and four groups of scraping blades 503 are respectively arranged along the center of the circular plate 606, and the scraping blades 503 are attached to the inner wall of the mixing box 1;

[0063] When the circular plate 606 rotates, it can drive the scraping knife 503 to rotate, so that the scraping knife 503 scrapes the inner wall of the mixing box 1, preventing the mixing box 1 from sticking to the cable material for a long time and affecting the subsequent heating effect and mixing degree of the cable material, thereby improving practicality.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
