Description

Technical Field

[0001] The utility model relates to the technical field of sheathing extruders, in particular to a sheathing extruder for wire production. Background Art

[0002] The cable protective sheath is mainly used to protect the wire core from being eroded by the surrounding environment. At the same time, it can play an insulating role and improve the use effect. When producing the cable protective sheath, first, an inner insulating layer needs to be coated on the wire core. An extruder is required to heat the raw materials to a molten state, uniformly mix them, and form them through a die, which is wrapped around the outside of the cable wire core, and then enters a cooling water tank for cooling and forming.

[0003] Therefore, a complete sheathing extruder for wire production is composed of a conveying structure, an extrusion structure, and a cooling structure. Currently, it is found that during the actual production process of wire sheathing extrusion, since there is still an exposed wire core for traction at the front end wrapped by the sheath after the wire is extruded, when it passes through the cooling structure during the conveying and cooling process, it is necessary to manually lift and traction it to lift its end above the water surface to avoid water entering the connection between the sheath and the wire core, which easily causes "sheath detachment". However, manually traction at the connection between the exposed wire core and the sheath easily has the following defects;

[0004] 1. Since the cooling tank has a certain length, within this range, the operator not only needs to keep enough strength in the arm to lift the cable above the coolant, but also needs to walk along with the conveying of the wire. Therefore, the actual operation is more inconvenient, requires multiple people to cooperate, and it is very easy to cause the cable to accidentally fall into the water tank and cause water ingress.

[0005] 2. Since the traction part needs to be exposed above the coolant, the rear part of the sheath at the connection between the sheath and the wire core will also be lifted into the air and cannot be cooled. Therefore, the operator mostly splashes water manually in the cooling tank for cooling, which further increases the difficulty of sheath production.

[0006] Therefore, a sheathing extruder for wire production is proposed. Utility Model Content

[0007] Based on this, in view of the above technical problems, it is necessary to provide a sheathing extruder for wire production. Through the design of a lifting structure and a cooling and temperature reduction structure, while realizing lifting and conveying, the cooling and temperature reduction of the area behind the connection between the sheath and the wire core are satisfied.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A sheathing extruder for wire production, including a conveying mechanism, an extrusion mechanism and a cooling tank, is characterized in that it further includes:

[0010] A sheathing extrusion end head, which is arranged on one side of the extrusion mechanism, and a wire input end head is also arranged on the other side of the extrusion mechanism;

[0011] Guide grooves, which are arranged on both side walls of the cooling tank for the installation of the lifting structure;

[0012] Wherein, the lifting structure includes two lifting rollers arranged corresponding to each other up and down and pressing members commonly arranged on both sides of the two lifting rollers. Under the action of the pressing members, the two lifting rollers can form a relative pressing trend;

[0013] Wherein, a support slider is fixed on the outer side of the lower lifting roller for sliding assembly with the guide groove. Under the action of the guide groove, the wire end head on the lifting structure can be lifted onto the cooling tank to realize conveying.

[0014] Further, the pressing member includes an upper connecting plate, a lower connecting plate and a connecting plate fixedly connected to the lower connecting plate;

[0015] The upper connecting plate and the lower connecting plate are respectively fixedly connected to the outer ends of the corresponding lifting rollers, and the connecting plate is slidably assembled with the upper connecting plate, and a spring connected to the connecting plate is fixed inside the upper connecting plate.

[0016] Further, a pressing gap is formed between the two lifting rollers. Under the action of the spring force, the size of the pressing gap in the natural state is smaller than the outer diameter of the cable.

[0017] Further, the guide groove includes a lifting section, a sliding section and a falling section;

[0018] Wherein, the lifting section, the sliding section and the falling section are sequentially connected end to end to jointly form the guide groove, and the lifting structure can slide along the direction of the guide groove under the action of the support slider.

[0019] Further, a cooling cavity is arranged in the cooling tank, and a coolant is loaded in the cooling cavity, and the liquid level height of the coolant is lower than the height of the sliding section.

[0020] Further, one of the support sliders extends outside the cooling tank and is also fixed with an auxiliary frame.

[0021] Further, a temperature reduction and cooling structure is commonly installed on the surfaces of the two support sliders for cooling and temperature reduction of the wire end head during the sliding process.

[0022] Further, the temperature reduction and cooling structure includes a support frame fixed on the surfaces of the two support sliders and a temperature reduction spray head rotatably arranged inside the support frame;

[0023] One side of the cooling nozzle is connected with a water supply hose for connection with an external water supply device.

[0024] One side inside the cooling tank is rotatably provided with a support roller;

[0025] The surface of the support slider is also threadedly connected with a fastening plate for forming a contact limit with the outside of the cooling tank.

[0026] Compared with the prior art, the utility model has the following beneficial effects:

[0027] The sheathing extruder for wire production provided by the utility model, by opening a guiding groove in a traditional cooling tank, enables the wire after being wrapped with the sheathing to be supported on a lifting structure and slide along the guiding groove, which not only ensures that it is lifted above the coolant and does not contact with it, but also can form support and sliding under the action of the guiding groove. The operator can realize the support and movement of the cable only through an auxiliary frame, which facilitates the better operation of wire sheathing extrusion;

[0028] At the same time, through the design of the synchronous movement of the cooling structure and the lifting structure, it can also cool the cable synchronously when lifting, pulling and sliding, and there is no need to adopt the cooling method of manually watering the cable exposed above the coolant, which further facilitates its actual application.

[0046] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0047] As described in the background art, 1. Since the cooling tank has a certain length, within this range, the operator not only needs to keep enough strength in the arm to lift the cable above the coolant, but also needs to walk along with the conveyance of the wire. Therefore, the actual operation is rather inconvenient, requiring multiple people to cooperate, and it is very easy to cause the cable to accidentally fall into the water tank and cause water ingress;

[0048] 2. Since the traction part needs to be exposed above the coolant, the rear part of the sheath at the connection of the sheath and the wire core will also be lifted into the air and cannot be cooled. Therefore, the operator mostly manually splashes water in the cooling tank for cooling, further increasing the difficulty of sheath production.

[0049] To solve this technical problem, the present utility model provides a sheath extruder for wire production, which is applied to the extrusion production of wire sheaths.

[0050] Specifically, please refer to Figures 1 - 6 , the sheathing extruder for wire production specifically includes a conveying mechanism 1, an extrusion mechanism 5 and a cooling tank 6, and is characterized in that it further includes:

[0051] A sheathing extrusion end 11, which is arranged on one side of the extrusion mechanism 5, and a wire input end 12 is also arranged on the other side of the extrusion mechanism 5;

[0052] A guiding groove 2, which is arranged on both side walls of the cooling tank 6 for the installation of the lifting structure 3;

[0053] Among them, the lifting structure 3 includes two lifting rollers 31 arranged corresponding to each other up and down and pressing members 32 commonly arranged on both sides of the two lifting rollers 31. Under the action of the pressing members 32, the two lifting rollers 31 can form a relative pressing trend;

[0054] Among them, a support slider 33 is fixed on the outside of the lower lifting roller 31 for sliding assembly with the guiding groove 2. Under the action of the guiding groove 2, the wire end on the lifting structure 3 can be lifted above the cooling tank 6 to realize conveying.

[0055] For the sheathing extruder for wire production provided by the present utility model, by opening the guiding groove 2 in the traditional cooling tank 6, the wire wrapped with the sheathing can be supported on the lifting structure 3 and slide along the guiding groove 2, which not only ensures that it is lifted above the coolant 62 and does not contact it, but also can form support and sliding under the action of the guiding groove 2. The operator only needs to use the auxiliary frame 34 to realize the support and movement of the cable, which facilitates the better operation of wire sheathing extrusion.

[0056] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0057] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0058] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0059] Embodiment 1

[0060] Please refer to Figures 1 - 7As shown in the figure, a sheathing extruder for wire production includes a conveying mechanism 1, an extrusion mechanism 5, and a cooling tank 6, and further includes: a sheathing extrusion end 11, which is arranged on one side of the extrusion mechanism 5, and a wire input end 12 is also arranged on the other side of the extrusion mechanism 5; a guide groove 2, which is arranged on the two side walls of the cooling tank 6 for the installation of the lifting structure 3. Among them, the lifting structure 3 includes two lifting rollers 31 arranged corresponding to each other up and down and pressing members 32 commonly arranged on both sides of the two lifting rollers 31. Under the action of the pressing members 32, the two lifting rollers 31 can form a relative pressing trend. Among them, a support slider 33 is fixed on the outside of the lower lifting roller 31 for sliding assembly with the guide groove 2. Under the action of the guide groove 2, the wire end on the lifting structure 3 can be lifted above the cooling tank 6 to realize conveying.

[0061] Please refer to Figure 5 、 Figure 6 The pressing member 32 includes an upper connecting plate 320, a lower connecting plate 321, and a connecting plate 322 fixedly connected to the lower connecting plate 321;

[0062] The upper connecting plate 320 and the lower connecting plate 321 are respectively fixedly connected to the outer ends of the corresponding lifting rollers 31, and the connecting plate 322 is slidably assembled with the upper connecting plate 320, and a spring 323 connected to the connecting plate 322 is fixed inside the upper connecting plate 320.

[0063] A pressing gap 324 is formed between the two lifting rollers 31. Under the elastic force of the spring 323, the size of the pressing gap 324 in the natural state is smaller than the outer diameter of the cable;

[0064] After the sheathing of the wire core is extruded through the extrusion mechanism 5, the connection between the front end of the extruded sheathing and the wire core cannot contact water, so it needs to be inserted into the pressing gap 324. After the wire core with the sheathing is placed in the pressing gap 324, the spring 323 is stretched. The stretched spring 323 will drive the upper connecting plate 320, the lower connecting plate 321 and the lifting rollers 31 connected thereto on it to approach each other, thereby forming an extrusion on the wire, so that the wire during the conveying process can drive the lifting structure 3 to move synchronously;

[0065] The wire during the conveying and moving process will drive the lifting structure 3 to slide along the direction of the guide groove 2, so as to ensure that it is isolated from the coolant below and avoid contact with water.

[0066] Embodiment 2

[0067] Further optimize the sheathing extruder for wire production provided in Embodiment 1. Specifically, as Figure 4As shown in the figure, the guiding groove 2 includes a lifting section 21, a sliding section 22, and a falling section 23. Among them, the lifting section 21, the sliding section 22, and the falling section 23 are connected end to end in sequence to jointly form the guiding groove 2. The lifting structure 3 can slide along the direction of the guiding groove 2 under the action of the supporting slider 33;

[0068] A cooling cavity 61 is provided in the cooling groove 6, and a coolant 62 is loaded in the cooling cavity 61. The liquid level height of the coolant 62 is lower than the height of the sliding section 22. An auxiliary frame 34 is fixed to the outside of the cooling groove 6 by extending one of the supporting sliders 33.

[0069] In the initial state, after the wire has just passed through the extrusion mechanism 5 for sheath extrusion, at this time, the lifting structure 3 is located in the lifting section 21. After the wire is placed in the pressing gap 324, as the wire is continuously conveyed, the lifting structure 3 will also slide in the lifting section 21 and finally slide into the sliding section 22 and the falling section 23. During this process, the operator can operate the auxiliary frame 34 according to the actual situation to ensure the stable lifting and conveying of the lifting structure 3 and the wire;

[0070] As Figure 7 shown, when the lifting structure 3 slides to the right side of the cooling groove 6, at this time, the front connection part of the wire core and the sheath also moves synchronously to this position. Since the subsequent wire is wrapped by a continuous sheath, it can be completely placed in the coolant 62 for cooling, without worrying about the problem of water ingress. At this time, the lower lifting roller 31 and the supporting roller 63 on one side of it can jointly form the support for the wire. Through the joint support of the two supporting rollers 63 at both ends, the wire can be input and output in the cooling groove 6, and the wire input into the cooling groove 6 can be cooled by the coolant 62;

[0071] When the sheath extrusion of this section of cable is completed and it is necessary to replace the next batch of wire cores for sheath extrusion, first move the lifting structure 3 from the falling section 23 to the position of the lifting section 21, and then repeat the above operation to ensure that the connection part of the wire core and the sheath still remains lifted above the coolant 62 to avoid water ingress.

[0072] Embodiment 3

[0073] The sheath extruder for wire production provided in Embodiment 1 or 2 is further optimized. As Figure 3 、 Figure 4 and Figure 5 shown, a cooling and temperature reduction structure 4 is jointly installed on the surfaces of the two supporting sliders 33, which is used to cool and reduce the temperature of the end of the wire during the sliding process. The cooling and temperature reduction structure 4 includes a support frame 41 fixed on the surfaces of the two supporting sliders 33 and a cooling spray head 42 rotatably arranged inside the support frame 41. One side of the cooling spray head 42 is connected with a water supply hose 43 for connection with an external water supply device;

[0074] In the process of the lifting structure 3 moving synchronously with the wire to form a support in the above-mentioned Embodiment 2, water supply can be carried out by connecting the water supply hose 43 to an external water supply device, so that the cooling nozzle 42 sprays water to spray and cool the area behind the connection of the wire core and the sheath and exposed outside the coolant 62. Thus, there is no need to manually splash water, which effectively facilitates the operation of personnel during the extrusion of the sheath.

[0075] Support rollers 63 are rotatably provided on both sides inside the cooling tank 6. A fastening disc 330 is also threadedly connected to the surface of the support slider 33 for forming a contact limit with the outside of the cooling tank 6.

[0076] When the lifting structure 3 moves in the falling section 23 and the connection of the wire core and the sheath has been conveyed to the rear of the cooling tank 6, and at this time when there is no need for the lifting structure 3 to move and support, the fastening disc 330 can be rotated so that one side of it is closely attached to the surface of the cooling tank 6, thereby forming a limit on the lifting structure 3 and the cooling structure 4 to ensure the fixation of its position and avoid affecting the subsequent conveyance of the wire.

[0077] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation" and the like shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0078] Obviously, the above-described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The preferred embodiments of the present utility model are shown in the drawings, but do not limit the patent scope of the present utility model. The present utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present utility model more thorough and comprehensive. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing specific embodiments, or perform equivalent replacements on some of the technical features. Any equivalent structure directly or indirectly using the content of the specification and drawings of the present utility model in other related technical fields is equally within the scope of the patent protection of the present utility model.
