Description

Technical Field

[0001] Embodiments of this disclosure relate to the field of extruder technology, and more specifically, to a cable extruder. Background Technology

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are used to transmit electrical energy or signals and are widely used in many fields such as power, communication and construction. In the production of cables, various raw materials such as polyvinyl chloride and polyethylene are usually put into an extruder. The raw materials are melted and heated by the extrusion cylinder of the extruder. After heating, the raw materials are conveyed and extruded by the rotation of the screw. The raw materials are finally formed by the mold to become the cable insulation layer or sheath.

[0003] During preparation, multiple raw materials need to be stirred and blended. Therefore, multiple raw materials need to be poured into a mixer for stirring and mixing beforehand. Then, the mixed raw materials are transferred and poured into the hopper of the extruder. This process is quite cumbersome and laborious. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a cable extruder to solve the technical problem in the prior art that the material needs to be mixed in a mixer before being transported and poured into the hopper of the extruder, which is quite troublesome and laborious.

[0005] According to one aspect, at least one embodiment of this disclosure provides a cable extruder, including an extruder body, and further including a feeding box, a mixing cylinder, a stirring assembly, an opening and closing assembly, and an opening and closing plate. The feeding box is through-connected and installed at the top of the extruder body, the mixing cylinder is through-connected and installed at the top of the feeding box, the stirring assembly is disposed on the mixing cylinder for stirring the raw materials in the mixing cylinder, the opening and closing assembly is disposed on the extruder body for dropping the stirred material into the interior of the extruder body, and the opening and closing plate is through-slidably installed inside the feeding box.

[0006] Furthermore, the stirring assembly includes a mounting plate, a first motor, a stirring shaft, and stirring rods. The mounting plate is fixedly installed on the top of the mixing cylinder, the first motor is mounted on the mounting plate, the stirring shaft is coaxially connected to the output end of the first motor, and a plurality of stirring rods are provided, all of which are fixedly installed on the side of the stirring shaft.

[0007] Furthermore, the opening and closing assembly includes a support cover, a reciprocating screw, a second motor, a synchronization component, and a support component. Two support covers are provided, and both support covers are fixedly installed on the top of the extruder body. The reciprocating screw is rotatably installed in one of the support covers, and a matching screw nut is installed on the reciprocating screw. The second motor is installed on the side of the support cover, and the output end of the second motor is coaxially connected to the reciprocating screw. The synchronization component is located in the other support cover, and the support component is located on the side of the feed box.

[0008] Furthermore, the synchronization component includes a sliding rod, a driving block, and a connecting rod. The sliding rod is fixedly installed inside another support cover, the driving block is slidably installed on the sliding rod, and the connecting rod is fixedly installed on the side of both the driving block and the lead screw nut. The side of the connecting rod is also fixedly installed on the side of the opening and closing plate.

[0009] Furthermore, the support assembly includes a sliding plate and a slider. The sliding plate is fixedly installed on the side of the feeding box, and two grooves are provided at the top of the sliding plate. There are two sliders, which are slidably installed in the grooves of the sliding plate, and the bottom end of the opening and closing plate is fixedly connected to the top end of the slider.

[0010] To prevent some raw materials from entering the mixing cylinder, the top of the opening and closing plate is further fitted to the bottom of the mixing cylinder.

[0011] In order to further impede the raw materials during mixing, the area of ​​the opening and closing plate is larger than the area of ​​the bottom end of the mixing cylinder.

[0012] In order to seal the mixing cylinder while stirring the raw materials, the mounting plate is further provided with cylinder covers hinged to both sides, and the cylinder covers match the top opening of the mixing cylinder.

[0013] The beneficial effects of the embodiments disclosed herein are as follows:

[0014] 1. In this disclosure, when extruding the cable, a certain amount of raw material is first poured into the mixing cylinder. At this time, the opening and closing plate can block the bottom of the mixing cylinder, and the raw material in the mixing cylinder can be stirred by the stirring component. After stirring, the stirred raw material can be directly dropped into the extruder body for subsequent extrusion.

[0015] 2. In this disclosure, after the various raw materials are mixed, the opening and closing assembly can disengage the opening and closing plate from the feeding box, so that the mixed raw materials fall into the extruder body. Furthermore, the opening and closing plate can block the raw materials during mixing to prevent them from falling.

[0016] In summary, this extruder, through the cooperation of the feeding box, mixing cylinder, stirring assembly, opening and closing assembly, and opening and closing plate, can mix various raw materials in the mixing cylinder. After mixing, the raw materials are directly dropped into the extruder body for subsequent extrusion. This is more convenient and labor-saving than mixing in a mixer and then transporting and pouring the raw materials into the extruder body. Attached Figure Description

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-7As shown, a cable extruder according to an embodiment of the present disclosure is illustrated, including an extruder body 1, a feeding box 2, a mixing cylinder 3, a stirring assembly, an opening and closing assembly, and an opening and closing plate 4. The feeding box 2 is installed through and connected to the top of the extruder body 1, the mixing cylinder 3 is installed through and connected to the top of the feeding box 2, the stirring assembly is disposed on the mixing cylinder 3 for stirring the raw materials in the mixing cylinder 3, the opening and closing assembly is disposed on the extruder body 1 for dropping the stirred material into the interior of the extruder body 1, and the opening and closing plate 4 is slidably installed through and connected to the feeding box 2.

[0033] like Figure 2 and Figure 4 As shown, during cable extrusion, because both sides of the mounting plate 5 are hinged with cylinder covers 18, and the cylinder covers 18 match the top opening of the mixing cylinder 3, opening the cylinder covers 18 allows a certain amount of raw material to be poured into the mixing cylinder 3. At this time, the opening and closing plate 4 is located in the feeding box 2. Because the top of the opening and closing plate 4 is in contact with the bottom of the mixing cylinder 3 and the area of ​​the opening and closing plate 4 is larger than the area of ​​the bottom of the mixing cylinder 3, the raw material is blocked. Then, the various raw materials are stirred in the mixing cylinder 3 by the stirring assembly. The stirring assembly includes the mounting plate 5, the first motor 6, the stirring shaft 7, and the stirring rod 8. The mounting plate 5 is fixedly installed. At the top of the mixing cylinder 3, the first motor 6 is mounted on the mounting plate 5. The stirring shaft 7 is coaxially connected to the output end of the first motor 6. Several stirring rods 8 are provided, and all stirring rods 8 are fixedly mounted on the side of the stirring shaft 7. Specifically, when the first motor 6 is started, the output end of the first motor 6 drives the stirring shaft 7 to rotate, and the stirring shaft 7 drives the stirring rods 8 to rotate, thereby stirring the raw materials in the mixing cylinder 3. Because the mixing cylinder 3 is an irregular conical cylinder, the lengths of the stirring rods 8 are different, so that the raw materials at different positions can be stirred. During stirring, the cylinder cover 18 can be closed to seal the mixing cylinder 3.

[0034] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, after mixing is complete, the opening and closing assembly moves the opening and closing plate 4, causing the mixed raw material to fall into the extruder body 1. The opening and closing assembly includes a support cover 9, a reciprocating screw 10, a second motor 12, a synchronization assembly, and a support assembly. There are two support covers 9, both of which are fixedly installed on the top of the extruder body 1. The reciprocating screw 10 is rotatably installed in one of the support covers 9, and a matching screw nut 11 is installed on the reciprocating screw 10. The second motor 12 is installed on the side of the support cover 9, and the output end of the second motor 12 is coaxially connected to the reciprocating screw 10. The synchronization assembly is located in the other support cover 9, and the support assembly is located in the feed box 2. On the side, the synchronization component includes a sliding rod 13, a driving block 14, and a connecting rod 15. The sliding rod 13 is fixedly installed inside another support cover 9. The driving block 14 is slidably installed on the sliding rod 13. The driving block 14 and the lead screw nut 11 are both fixedly installed with connecting rods 15 on their sides. The side of the connecting rod 15 is fixedly installed on the side of the opening and closing plate 4. The support component includes a sliding plate 16 and a slider 17. The sliding plate 16 is fixedly installed on the side of the feeding box 2. The top of the sliding plate 16 has two grooves. There are two sliders 17. The two sliders 17 are slidably installed in the grooves of the sliding plate 16. The bottom end of the opening and closing plate 4 is fixedly connected to the top end of the slider 17.

[0035] Specifically, the second motor 12 is started, and the output end of the second motor 12 drives the reciprocating screw 10 to rotate inside the support cover 9, thereby driving the screw nut 11 to move on the reciprocating screw 10. It should be added that the surface of the reciprocating screw 10 is machined with a special spiral groove, and the screw nut 11 is fitted on the outside of the reciprocating screw 10. The inner wall is machined with a protruding ridge that matches the spiral groove of the reciprocating screw 10. The two form a meshing pair. This is a well-known technology and will not be described in detail. Under the connection of the connecting rod 15 and the opening and closing plate 4, the connecting rod 15 and the driving block 14 at the other end are driven to move on the sliding rod 13. Thus, under the sliding of the slider 17, the opening and closing plate 4 is driven to move on the sliding plate 16, disengaging from the feeding box 2, so that the raw material falls into the extruder body 1. It should be added that a rubber sealing strip is installed at the gap between the opening and closing plate 4 and the feeding box 2 to ensure that the raw material will not escape from the gap during mixing.

[0036] Working principle: When extruding the cable, the cylinder cover 18 is opened and a certain amount of raw material is poured into the mixing cylinder 3. The first motor 6 is started. The output end of the first motor 6 drives the stirring shaft 7 to rotate. The stirring shaft 7 drives the stirring rod 8 to rotate, thereby stirring the raw material in the mixing cylinder 3. After stirring is completed, the second motor 12 is started. The output end of the second motor 12 drives the reciprocating screw 10 to rotate in the support cover 9, thereby driving the screw nut 11 to move on the reciprocating screw 10. Under the connection of the connecting rod 15 and the opening and closing plate 4, the connecting rod 15 and the driving block 14 at the other end move on the sliding rod 13. Thus, under the sliding of the slider 17, the opening and closing plate 4 moves on the sliding plate 16, disengaging from the feeding box 2, so that the raw material falls into the extruder body 1. The raw material is heated and melted by the extrusion cylinder of the extruder body 1. Then, through the rotation of the internal screw, the raw material is extruded at the outlet of the extruder body 1, thereby forming an insulating protective layer on the outside of the cable.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
