Abstract
Description
Technical Field
[0001] The utility model relates to the field of cable extrusion, in particular to an extrusion production line. Background Art
[0002] The cable is finally formed after being processed by extrusion and the like in an extrusion production line. However, in the prior art, the structure of the commonly used extrusion production line is too simple, resulting in low working efficiency, which is not conducive to improving the production efficiency of the cable.
[0003] If the production line only uses one pay-off rack, only one reel of cable can be extruded at a time. Because when the cable is extruded, a reel of conductor on the pay-off rack is used up, and the worker needs to stop the machine and replace a new reel of conductor behind the pay-off rack. The new reel of conductor needs to be re-threaded through the extruder head, glued side by side, and the cable core is adjusted. This wastes time and has low production efficiency. For another example, if the production line only uses one extruder head, the insulation layer and sheath on the outer periphery of the conductor need to be extruded and irradiated separately, and the product cannot be formed in one go, which wastes time and has low production efficiency.

[0033] The utility model provides an extrusion production line in an embodiment, which improves the structure of the extrusion production line in the cable production process, thereby effectively improving the production efficiency and quality thereof.
[0034] like Figure 1 As shown, Figure 1 The schematic diagram of the structure of an extrusion production line provided in the embodiment of the utility model is shown in FIG. The extrusion production line is composed of a plurality of devices with different functions, each of which can achieve different production purposes. After the plurality of different devices work together, a finished cable product is finally obtained.
[0035] Specifically, the extrusion production line in the embodiment of the utility model includes a plurality of pay-off devices 101, a storage pulley 102, a pay-off auxiliary device 1013, a conductor preheater 103, an extrusion mechanism 104, a diameter gauge 105, a cooling device 106, a drying device 107 and a take-up device 108. When the extrusion production line works normally, the above-mentioned different functional modules or devices cooperate with each other and are processed in the corresponding front and back processing sequence, thereby realizing the production and molding of the line.
[0036] Specifically, the pay-off device 101 can actively pay-off the wire. Two pay-off devices 101 provided in the embodiment of the utility model can be provided: the two pay-off devices 101 are provided independently, and each pay-off device 101 can include a wire and a winding wheel, on which a plurality of turns of the wire to be processed are wound. When the wire on one of the winding wheels is used up, the wire on the other winding wheel can be replenished in time, thereby avoiding the problem of affecting the productivity of the pay-off device 101 due to untimely wire replacement by providing two winding wheels.
[0037] Furthermore, after the wire to be processed on the wire-releasing device 101 is guided by the wire-releasing auxiliary device 1013, it will continue to be transmitted to the downstream of the extrusion production line. In the embodiment of the present application, the wire-releasing auxiliary device 1013 can be arranged horizontally. Optionally, the wire-releasing auxiliary device 1013 can be arranged as a steering wheel, and the transmitted wire is wound around the steering wheel, so that the wire is transmitted and turned through the steering wheel. In the utility model, the transmission effect of the wire is improved by the wire-releasing auxiliary device 1013. At the same time, a guide wheel can be arranged between the wire-releasing auxiliary device 1013 and the first wire storage device 701, and the horizontal wire is transmitted upward through the guide wheel.
[0038] In this embodiment, the first wire storage device 701 is suspended, such as being arranged at a corresponding position above the extrusion production line. In this application, by arranging the first wire storage device 701 at the top, when the wire is put down, under the action of gravity, it has a better stretching effect, and the first wire storage device 701 can also provide enough wire for subsequent processing and prevent the problem of winding during the wire release process.
[0039] In the utility model, the first wire storage device 701 can be set as a wire storage rack, and the wire is coiled on the wire storage rack. When it is necessary to release the wire forward, the wire storage disc on the wire storage rack is operated to allow the wire to be released downward. In the process of releasing the wire, the wire is then acted upon by a wire storage traction wheel 102 arranged downstream thereof, and the wire storage traction wheel 102 can tighten the wire and improve the effect of lowering the wire. Among them, the wire storage traction wheel 102 can be set as a plurality of pulleys, and the pulleys can change the position of the wire entering the subsequent device, so that the running direction of the wire is parallel to the extrusion production line. And after the wire is guided and pre-tightened by the pulley, the originally loose wire can be tightened for subsequent use.
[0040] Meanwhile, after being processed by the wire storage traction wheel 102, the wire will enter the conductor preheater 103, which is arranged downstream of the wire storage traction wheel 102. The conductor preheater 103 is mainly used to heat the wire, and its heating temperature is set to 180°C~220°C, such as 200°C. After the wire is preheated by the conductor preheater 103 in the utility model, the extruded cable has a good appearance and is not prone to poor appearance such as bulging.
[0041] Among them, the extrusion production line also includes a pressure roller device 200, which is arranged between the conductor preheater 103 and the extrusion mechanism 104. After the conductor preheater 103 preheats the wire, it enters the pressure roller device. In the utility model, the pressure roller device 200 includes at least 4 rollers. Specifically, the pressure roller device 200 is arranged to be 5 rollers staggered up and down, and the spacing between two adjacent rollers is small, so as to ensure the rolling of the wire. And to the greatest extent possible, it is ensured that the wire can smoothly enter the extrusion mechanism 104 later. During the extrusion process, the more stable the state of the wire when entering the extrusion mechanism 104, the better the appearance of the extruded insulated wire core. In the utility model, the wire processed by the pressure roller device 200 is further transmitted to the extrusion mechanism 104 and extruded by the extrusion mechanism 104.
[0042] In the embodiment of the present application, the extrusion mechanism 104 may include a first extrusion head 301 and a second extrusion head 302. The second extrusion head 302 is arranged downstream of the first extrusion head 301. After extrusion by two different extrusion heads, different insulation material layers are formed around the wire.
[0043] Specifically, a cooling device 106, a drying device 107, a diameter gauge 105, and a powdering device 300 are sequentially arranged between the first extrusion head 301 and the second extrusion head 302. The first extrusion head 301 extrude the wire and plasticize the wire through the first extrusion head 301, so as to form an insulating layer wrapped around the wire. At the same time, the wire plasticized by the first extrusion head 301 will be transferred to the first water tank 1061 corresponding to the cooling device 106. The first water tank 1061 can be set as a single-layer water tank, and the extruded wire is cooled and shaped by the first water tank 1061. A drying device 107 can also be set on the first water tank 1061. The drying device 107 can dry the cleaned wire to prevent the water on the wire from affecting its subsequent process. In this embodiment, after passing through the cooling device 106 and the drying device 107 , the wire material enters the diameter gauge 105 , and its yield is tested by the diameter gauge 105 , thereby ensuring the quality of the wire material.
[0044] Furthermore, after the wire is cooled and shaped by the cooling device 106, dried by the drying device 107, and detected by the diameter gauge 105, it will be transferred to the powdering device 300. The powdering device 300 can form a covering layer on the periphery of the insulating layer formed by the first extrusion head 301. When it passes through the second extrusion head 302 corresponding to the extrusion mechanism 104 again, a protective layer will be formed on the periphery of the insulating layer under the extrusion of the second extrusion head 302. In this way, in this embodiment, by providing two different extrusion heads, the two different extrusion heads can form an insulating layer around the wire respectively, and form a protective layer around the insulating layer. These two layers can effectively improve the quality of the wire.
[0045] Among them, the caliber of the second extrusion head 302 is larger than the caliber of the first extrusion head. By controlling the caliber of the second extrusion head 302, the molding accuracy is further improved, and the molding of different insulation layers and sheath layers is achieved. When setting the extrusion mechanism of the utility model, the extrusion mechanism 104 also includes a host control cabinet, which can be set after the extrusion head and close to the extrusion production line. The host control cabinet is used to control the temperature of the plasticized insulation material of the extrusion material of the head, the machine traction speed, the host speed, the production speed, etc. of the extrusion mechanism 104 when extruding the wire.
[0046] Furthermore, in the utility model, another cooling device 106, another drying device 107 and another diameter gauge 105 are sequentially arranged downstream of the second extrusion head 302. After being processed by the second extrusion head 302, the wire enters another cooling device 106, which includes a second water tank 1062. The wire is transmitted to the second water tank 1062, and another drying device 107 is also arranged on the second water tank 1062. In this embodiment, since the protective sleeve of the outer ring of the wire formed after extrusion by the second extrusion head 302 is relatively thick, the second water tank 1062 can be set as a double-layer water tank. The cooling and shaping effect of the wire after extrusion is accelerated by the double-layer water tank. Specifically, in this embodiment, the extruded cable is transported forward after being pulled by the cabinet traction wheel corresponding to the double-layer water tank, and cyclic cooling is performed, and finally, under the traction of the cabinet traction wheel, it enters the drying device 107. At this time, the drying device 107 is mainly used to blow off the water droplets of the cable product from the water tank to keep the cable dry. In the utility model, the high-efficiency extruder has a double-layer water tank, and the extruded product passes through the traction wheel to realize the double-layer water tank circulation cooling of the cable. Not only the cooling effect is improved, but also the length of the production line is shortened and the floor space of the production line is reduced.
[0047] like Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the second water tank provided in an embodiment of the utility model. In the utility model, when the double-layer water tank corresponding to the second water tank 1062 is set, it includes two single-layer water tanks 201 arranged in sequence in the vertical direction. And the upper single-layer water tank 201 is arranged corresponding to the lower single-layer water tank 201. In the utility model, in order to ensure the transmission effect of the cable in the water tank, a plurality of guide wheels 202 are also arranged in the water tank. The guide wheel 202 is arranged in the water body of the water tank, and the extruded cable is placed on the guide wheel 202, and is continuously transmitted forward through the guide wheel 202. In the utility model, a plurality of guide wheels 202 are arranged in the water tank to further reduce the resistance in the cable transmission process, thereby achieving the purpose of improving production efficiency and reducing costs.
[0048] In this embodiment, after the wire passes through another cooling device 106 and another drying device 107, it will enter another caliper 105. The outer diameter of the product can be measured in real time through the caliper 105, so as to ensure the size and quality of the wire after extrusion. Furthermore, the caliper 105 also includes an early warning module, which is connected to the caliper 105 signal. When the diameter of the wire exceeds the threshold, the early warning module will give an early warning. If the diameter of the wire after extrusion is greater than the threshold A, the early warning module will give an early warning.
[0049] Furthermore, the extrusion production line provided in the utility model also includes a spark machine 601 and a meter. The spark machine 601 is arranged downstream of the second water tank 1062. After the cable is dried, it passes through the spark machine. The spark machine uses the process of high voltage and low current discharge to detect defects such as air holes, foreign metal, and product damage in the cable to ensure product quality. After the cable spark machine 601 detects the formed cable, it enters the meter card slot. The cable is counted by driving the meter wheel. The meter can be set downstream of the spark machine 601, and a printer can also be set downstream of the meter to mark the cable by the printer. Figure 1 The meter counter and the inkjet printer are not shown in the figure. The meter counter is used to obtain the cable length, and the inkjet printer is used to print the cable. The meter counter in the utility model is provided with a slot. After the cable passes through the meter counter slot, the cable transmission is more stable and not easy to shake, and it is convenient for the subsequent printer to print the code.
[0050] Furthermore, the printed cable is acted upon by another wire storage traction wheel 102 and enters the second wire storage device 702. In the present invention, the second wire storage device 702 is also suspended and can be set to the same specifications as the first wire storage device 701, or can be improved according to needs. The processed cable can be wound around the second wire storage device 702, and the extruded finished cable can be stored through the second wire storage device 702. In this example, both wire storage devices are provided with a sensing device. When the conductor or cable slides out of the traction wheel groove on the wire storage device, the sensing device is triggered to sound an alarm, thereby effectively avoiding the production stoppage caused by the conductor or cable falling off the wire storage rack.
[0051] Furthermore, a take-up device 108 is provided downstream of the second wire storage device 702. The take-up device 108 can be provided as a cable reel. The cable reel rotates backward to provide traction, so that the extruded cable product is actively wound on the cable reel to complete the cable product take-up. When the take-up device 108 is provided, two different cable reels can be provided. Each cable reel can take up 1000m to 3000m of formed cable, thereby increasing the take-up length and improving productivity.
[0052] In the embodiment of the utility model, an induction alarm device is also provided on the take-up device 108. When a cable reel is about to be used up, the device sends out an alarm to remind the operator to crimp the cable, thereby avoiding short-line or shutdown problems of the extrusion production line and improving production efficiency.
[0053] The above description is only a partial implementation method of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the technical concept of the present invention, other similar implementation methods based on the technical ideas of the present invention are also within the protection scope of the embodiments of the present invention.
