Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to a colorant extrusion device for a cable extruder. Background Technology

[0002] Extruders are indispensable in the cable production process. A cable extruder is a device that feeds plastic material into the hopper and uses the pressure and shearing force generated by the rotating screw to fully plasticize and uniformly mix the material before extruding it to the extrusion head and forming it into shape.

[0003] Replacing the extruder head is a critical operation in cable extrusion production, and its necessity involves multiple factors such as process adjustment, equipment maintenance, and quality optimization. In existing technologies, the extruder head is generally fixed to the extrusion port of the extruder with multiple bolts. When disassembling and replacing the extruder head, it is necessary to remove and install multiple bolts, which takes too long. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a colorant extrusion device for a cable extruder, so as to solve the problem that multiple bolts need to be disassembled and replaced when the extrusion head is disassembled and replaced, and the disassembly and assembly time is too long.

[0005] To achieve the above objectives, this utility model provides a colorant extrusion device for a cable extruder, comprising a mounting box and two extrusion heads. A translation seat is provided between the two extrusion heads. The mounting box is equipped with a translation structure for driving the translation seat to move. A support shaft passes through the translation seat and is rotatably connected to the translation seat. A rotating frame is fixedly connected to the side of the support shaft away from the mounting box. The rotating frame has two mounting holes that are respectively adapted to the extrusion heads. At least one slot is provided on the inner wall of the mounting hole. A plug is provided in the slot. The extrusion head passes through the corresponding mounting hole, and the plug and the corresponding extrusion head are fixedly connected. The translation seat is equipped with a rotating mechanism for driving the support shaft to rotate.

[0006] Preferably, the translation structure includes two lead screws rotatably mounted on the mounting box. The lead screws are fitted with threaded sleeves, and the threaded sleeves are fixedly connected to the translation seat. The mounting box is equipped with a driver for driving the two lead screws to rotate.

[0007] Preferably, the driver includes a rotating shaft rotatably mounted in a mounting box, a servo motor fixedly connected to the outer wall of the mounting box, and the output end of the servo motor passing through the mounting box. The output end of the servo motor is fixedly connected to the rotating shaft, and two worm gears are fixedly sleeved on the outside of the rotating shaft. The threads on the two worm gears are in the same direction, and worm wheels located in the mounting box are fixedly mounted on the worm gears. The worm wheels mesh with the corresponding worm gears.

[0008] Preferably, the rotating mechanism includes a support base disposed on the side of the support shaft facing the mounting box, a sliding groove is provided on the support shaft, a slider is slidably disposed in the sliding groove, one end of the slider is fixedly connected to the support base, and the other end of the slider is connected to the inner wall of the sliding groove by a tension spring, a guide groove is provided on the inner wall of the sliding groove, a guide block is slidably disposed in the guide groove, and the guide block is fixedly connected to the slider, and two positioning posts are fixedly connected on the side of the support base facing the translation seat, and two positioning holes adapted to the positioning posts are provided on the translation seat, and the end of the positioning post away from the support base passes through the corresponding positioning hole.

[0009] Preferably, an elastic pad is fixedly connected to the side of the support shaft facing the support base, and the elastic pad is in contact with the support base.

[0010] Preferably, the support base is rotatably connected to an iron plate on the side facing the mounting box, and an iron block is fixedly connected to the side of the mounting box facing the iron plate.

[0011] The beneficial effects of this utility model are as follows: When it is necessary to replace the extruder head installed with the extrusion port, the translation structure drives the translation seat and rotating frame to move away from the extruder. When the extruder head is no longer in contact with the extrusion port, the operator drives the support shaft and rotating frame to rotate 180 degrees through the rotation mechanism, so that another extruder head to be installed rotates to the side of the extrusion port, and the extruder head to be disassembled rotates to the bottom. The translation structure drives the translation seat and rotating frame to move towards the extruder again, so that the extruder head located above is in contact with the extrusion port again. The operator drives the extruder head located below to move relative to the rotating frame, so that the extruder head disengages from the mounting hole and the insert on the extruder head disengages from the slot, thus allowing the extruder head to be disassembled. This facilitates the replacement of the extruder head without the need to remove and install multiple bolts, changes the installation method of the extruder head, shortens the time for replacing the extruder head, and thus reduces the downtime of the extruder, thereby improving production efficiency.

[0022] This specification provides one or more embodiments of a colorant extrusion device for a cable extruder, such as... Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the extruder includes a mounting box 1 and two extrusion heads 6. A translation seat 2 is provided between the two extrusion heads 6. The mounting box 1 is equipped with a translation structure for driving the translation seat 2 to translate. A support shaft 3 passes through the translation seat 2 and is rotatably connected to the translation seat 2. A rotating frame 4 is fixedly connected to the side of the support shaft 3 away from the mounting box 1. The rotating frame 4 has two mounting holes 5 that are respectively adapted to the extrusion heads 6. At least one slot 8 is provided on the inner wall of the mounting hole 5. A plug 7 is provided in the slot 8. The extrusion head 6 passes through the corresponding mounting hole 5, and the plug 7 is fixedly connected to the corresponding extrusion head 6. The translation seat 2 is equipped with a rotating mechanism for driving the support shaft 3 to rotate. The operator installs the mounting box 1 on the frame of the extruder, with the upper extrusion head 6 corresponding to the extrusion port of the extruder. The translation structure drives the translation seat 2 to translate, so that the translation seat 2 drives the rotating frame 4 and the extrusion head 6 to translate synchronously through the support shaft 3. Finally, the upper extrusion head 6 abuts against the extrusion port of the extruder, and the plug 7 moves away from the extrusion head 6. When the extrusion head 6, which is installed with the extrusion port, needs to be replaced, the translational structure drives the translational seat 2 and the rotating frame 4 to move away from the extruder. When the extrusion head 6 is no longer in contact with the extrusion port, the operator drives the support shaft 3 and the rotating frame 4 to rotate 180 degrees through the rotation mechanism, so that another extrusion head 6 that needs to be installed rotates to the side of the extrusion port. The extrusion head 6 that needs to be disassembled rotates to the bottom. The translational structure drives the translational seat 2 and the rotating frame 4 to move towards the extruder again, so that the extrusion head 6 located above is in contact with the extrusion port again. The operator drives the extrusion head 6 located below to move relative to the rotating frame 4, so that the extrusion head 6 disengages from the mounting hole 5 and the insert 7 on the extrusion head 6 disengages from the slot 8. The extrusion head 6 that needs to be disassembled can then be removed, making it easy to replace the extrusion head 6 without removing and installing multiple bolts. This changes the installation method of the extrusion head 6, shortens the replacement time of the extrusion head 6, and thus reduces the downtime of the extruder, thereby improving production efficiency.

[0023] In embodiments of this utility model, such as Figure 1 and Figure 3As shown, the translation structure includes two lead screws 9 rotatably mounted on the mounting box 1. A threaded sleeve 10 is fitted around the lead screw 9, and the threaded sleeve 10 is fixedly connected to the translation seat 2. The mounting box 1 is equipped with a driver for driving the two lead screws 9 to rotate. The driver includes a rotating shaft 25 rotatably mounted inside the mounting box 1. A servo motor 13 is fixedly connected to the outer wall of the mounting box 1, and the output end of the servo motor 13 passes into the mounting box 1. The output end of the servo motor 13 is fixedly connected to the rotating shaft 25. Two worm gears 12 are fixedly fitted around the rotating shaft 25. The threads on the two lead screws 9 are in the same direction. A worm wheel 11 is fixedly mounted on the lead screw 9 inside the mounting box 1, and the worm wheel 11 meshes with the corresponding worm gear 12. The servo motor 13 drives the rotating shaft 25 and the worm gear 12 to rotate, and the worm gear 12 drives the lead screw 9 to rotate through the worm wheel 11. The lead screw 9 drives the threaded sleeve 10 and the translation seat 2 to move horizontally relative to the mounting box 1, thereby driving the extruder head 6 to move towards or away from the extruder.

[0024] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 5As shown, the rotating mechanism includes a support base 14 disposed on the side of the support shaft 3 facing the mounting box 1. A slide groove 15 is provided on the support shaft 3, and a slider 16 is slidably disposed in the slide groove 15. One end of the slider 16 is fixedly connected to the support base 14, and the other end of the slider 16 is connected to the inner wall of the slide groove 15 by a tension spring 17. A guide groove 18 is provided on the inner wall of the slide groove 15, and a guide block 19 is slidably disposed in the guide groove 18. The guide block 19 is fixedly connected to the slider 16. Two positioning posts 21 are fixedly connected on the side of the support base 14 facing the translation seat 2. Two positioning holes adapted to the positioning posts 21 are provided on the translation seat 2. 20, and the end of the positioning post 21 away from the support base 14 passes through the corresponding positioning hole 20. The side of the support shaft 3 facing the support base 14 is fixedly connected to an elastic pad 22, and the elastic pad 22 is in contact with the support base 14. The side of the support base 14 facing the mounting box 1 is rotatably connected to an iron plate 23, and the side of the mounting box 1 facing the iron plate 23 is fixedly connected to an iron block 24. When the extrusion head 6 needs to be replaced, the translation seat 2 and the rotating frame 4 are driven to move towards the mounting box 1 through the translation structure. When the iron plate 23 and the iron block 24 are in contact, the iron plate 23 is fixed relative to the iron block 24 and the mounting box 1. Then, the translation seat 2 and the rotating frame 4 are driven to move towards the mounting box 1 through the translation structure. The rotating frame 4 moves away from the mounting box 1, causing the support shaft 3 to move relative to the slider 16 and the support base 14, thus disengaging the positioning pin 21 from the positioning hole 20. The tension spring 17 is then stretched, releasing the locking relationship between the support shaft 3 and the translational seat 2. The operator drives the rotating frame 4, support shaft 3, slider 16, and support base 14 to rotate relative to the iron plate 23, causing the rotating frame 4 to rotate 180 degrees. At this point, the guide block 19 abuts against the inner wall of the guide groove 18 on the side facing the support base 14. The translational structure drives the translational seat 2 to move again away from the mounting box 1. The support shaft 3 then moves away from the mounting box 1. The slider 16, support base 14, and iron plate 23 are driven to move synchronously to prevent the iron plate 23 from contacting the iron block 24. The tension spring 17 can then pull the slider 16 and support base 14 toward the support shaft 3 so that the end of the positioning post 21 is inserted back into the corresponding positioning hole 20. The support shaft 3 is fixed relative to the translation seat 2, and the support base 14 is in contact with the elastic pad 22. The elastic pad 22 provides elastic buffering to prevent the support base 14 from making hard contact with the support shaft 3. This allows the rotating frame 4 to rotate 180 degrees, facilitating the switching of the positions of the two extrusion heads 6 and making it convenient to replace the extrusion heads 6.
