Description

Technical Field

[0001] This utility model relates to the field of cable production equipment technology, and more specifically, to a multi-station material conveying and connecting device for cable production. Background Technology

[0002] In cable production, copper wires twisted into bundles are coated with an extruder to form the overall sheath, and then cooled and molded. During the extrusion process, plastic granules need to be added continuously. However, because the feed end of the extruder is high, it is often necessary to manually climb the platform at regular intervals to add the raw materials, which is very laborious. At the same time, since the raw materials are usually packaged in bags, the openings often cannot be opened quickly, which further reduces production efficiency and increases the labor intensity of workers.

[0003] In actual use, the packaging bags need to be repeatedly filled during the process of feeding different plastic granule raw materials. This process requires frequent replacement of different plastic granule raw materials, which will affect the efficiency of cable production. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-station material conveying and connecting device for cable production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-station material conveying and connecting device for cable production includes a mixing cylinder. An outer frame is fixedly connected to the outside of the mixing cylinder. A hopper is fixedly connected to the bottom of the mixing cylinder, and an electrically controlled butterfly valve is installed inside the hopper. A servo motor is fixedly connected to the upper surface of the mixing cylinder, and a rotating shaft is fixedly connected to the output end of the servo motor. The rotating shaft extends through the inside of the mixing cylinder and into its interior. A heater is installed inside the mixing cylinder. A multi-position feeding mechanism is provided at the top of the mixing cylinder. The multi-position feeding mechanism includes multiple supports, the bottom ends of which are connected to the mixing cylinder... The upper surface of the mixing cylinder is fixedly connected to a servo motor. A servo motor is fixedly connected to one side of the support. A turntable is fixedly connected to the output end of the servo motor. A feed hopper is fixedly connected to the top of the servo motor. Multiple support rods are fixedly connected to the inner side of the feed hopper. An extension arm is hinged to one side of the support rod. An electric push rod is hinged to one side of the extension arm. One end of the electric push rod is hinged to the inner side of the feed hopper. A blade is fixedly connected to one end of the extension arm. A conveying pipe is fixedly connected to the bottom of the feed hopper. The bottom end of the conveying pipe is connected to the upper surface of the mixing cylinder. A mixing mechanism is provided inside the mixing cylinder.

[0007] By adopting the above technical solution: setting up multiple feeding hoppers to feed various materials individually, and combining multiple expandable extension arms and blades to assist in opening and discharging bagged materials, the feeding process is optimized and blockages are reduced. Furthermore, servo motors and turntables are used to assist in discharging materials, thereby improving the continuity of material feeding.

[0008] As a further description of the above technical solution: the mixing mechanism includes two fixed frames, the inner side of the fixed frame is fixedly connected to the outer side of the rotating shaft, three scrapers are fixedly connected to the outer side of the fixed frame, two agitators are fixedly connected to the outer side of the scrapers, a spiral blade is fixedly connected to the bottom end of the rotating shaft, an outer cylinder is fixedly connected to the bottom end of the hopper, a servo motor is fixedly connected to one side of the outer cylinder, a rotating shaft is fixedly connected to the output end of the servo motor, the outer side of the rotating shaft is rotatably connected to the inner side of the outer cylinder, a spiral conveyor is fixedly connected to the outer side of the rotating shaft, and multiple protruding rods are fixedly connected to one side of the spiral conveyor.

[0009] By adopting the above technical solution: using two fixed frames, a stirring frame and a spiral blade to stir the molten material inside the mixing drum, and cooperating with three scrapers to scrape the inner wall of the mixing drum, the material inside the mixing drum is fully stirred. Then, by using the reverse rotation of the scrapers, the material on the inner wall of the mixing drum can be conveyed downwards to reduce the residue on the inner wall when the mixing drum outputs material.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By setting up multiple feeding mechanisms, compared with existing technologies, multiple independent feeding hoppers and conveying pipes can effectively prevent different types and colors of materials from mixing with each other, ensuring the accuracy and consistency of the final cable protection layer composition. Combined with the expansion of multiple extension arms, it assists in the smooth feeding of bagged materials, reduces the number of times operators repeatedly tap the material bags, reduces labor intensity, reduces downtime for material changes, and improves production efficiency and continuity.

[0012] 2. By setting up a mixing mechanism, compared with the existing technology, the continuous rotation of three scrapers can continuously scrape off the material adhering to the inner wall of the mixing cylinder and bring it back to the main flow area to participate in the mixing, eliminating the stagnant area near the cylinder wall. Combined with the stirring frame and multiple protruding rods to assist in the full mixing and stirring of the material during the melting and conveying process, the mixing uniformity and dispersion effect are improved.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The embodiments disclosed in this application are as follows: Figure 1-5The multi-station material conveying and connecting device for cable production shown includes a mixing cylinder 1, an outer frame 2 fixedly connected to the outside of the mixing cylinder 1, a feeding hopper 3 fixedly connected to the bottom of the mixing cylinder 1, an electrically controlled butterfly valve 4 installed inside the feeding hopper 3, a servo motor 5 fixedly connected to the upper surface of the mixing cylinder 1, a rotating shaft 6 fixedly connected to the output end of the servo motor 5, the outer side of the rotating shaft 6 penetrating the inner side of the mixing cylinder 1 and extending into the interior of the mixing cylinder 1, a heater 7 installed inside the mixing cylinder 1, and a multi-position feeding mechanism provided at the top of the mixing cylinder 1; the multi-position feeding mechanism includes multiple supports 8, the bottom end of the supports 8 fixedly connected to the upper surface of the mixing cylinder 1, a second servo motor 9 fixedly connected to one side of the supports 8, a turntable 15 fixedly connected to the output end of the second servo motor 9, and a top end of the second servo motor 15 fixedly connected to... A feeding hopper 10 is connected to the inside of the feeding hopper 10, and multiple support rods 11 are fixedly connected to the inside of the feeding hopper 10. An extension arm 12 is hinged to one side of the support rod 11, and an electric push rod 13 is hinged to one side of the extension arm 12. One end of the electric push rod 13 is hinged to the inside of the feeding hopper 10, and a blade 14 is fixedly connected to one end of the extension arm 12. A conveying pipe 16 is fixedly connected to the bottom of the feeding hopper 10, and the bottom end of the conveying pipe 16 is connected to the upper surface of the mixing cylinder 1. A mixing mechanism is set inside the mixing cylinder 1. The extension and retraction of multiple electric push rods 13 drives the extension arm 12 to deflect at one end of the corresponding support rod 11. Under the expansion of multiple extension arms 12 and blades 14, the opening of the material packaging bag is enlarged to assist the material in feeding. Multiple feeding hoppers 10 and conveying pipes 16 can improve the continuity of material feeding.

[0022] Reference Figure 1 , Figure 4 and Figure 6 As shown, the mixing mechanism includes two fixed frames 17. The inner side of the fixed frame 17 is fixedly connected to the outer side of the rotating shaft 6. Three scrapers 18 are fixedly connected to the outer side of the fixed frame 17. Two agitators 19 are fixedly connected to the outer side of the scrapers 18. A spiral blade 20 is fixedly connected to the bottom end of the rotating shaft 6. An outer cylinder 21 is fixedly connected to the bottom end of the hopper 3. A servo motor 22 is fixedly connected to one side of the outer cylinder 21. A rotating shaft 23 is fixedly connected to the output end of the servo motor 22. The outer side of the rotating shaft 23 is rotatably connected to the inner side of the outer cylinder 21. A spiral conveyor blade 24 is fixedly connected to the outer side of the rotating shaft 23. Multiple protruding rods 25 are fixedly connected to one side of the spiral conveyor blade 24. The two fixed frames 17 and three scrapers 18 are used to mix the molten material. The spiral scrapers 18 scrape the material remaining on the inner wall of the mixing cylinder 1. At the same time, the spiral blade 20 assists in conveying the material downward, so that the material can be fully mixed and the discharge efficiency can be improved.

[0023] The working principle of this utility model is as follows: When conveying materials, multiple bags containing materials are first placed above the four feed hoppers 10 at the top of the mixing drum 1. The bags are then perforated and cut by the extension arm 12 and the blade 14. Next, multiple electric push rods 13 inside the corresponding feed hopper 10 are activated to pull the extension arm 12, which rotates around the support rod 11. This allows the electric push rods 13 and the blade 14 to widen the opening of the bags, allowing the materials inside to fall into the feed hopper 10. When materials need to be added to the mixing drum 1, the corresponding servo motor 2 9 is activated to rotate the turntable 15 at the bottom of the feed hopper 10. This allows the materials inside the feed hopper 10 to pass through the turntable 15 and fall along the conveying pipe 16 into the mixing drum 1. Simultaneously, the heater 7 is activated to heat the inside of the mixing drum 1. After a batch of materials is placed inside the mixing drum 1, the servo motor 1 5 and the rotating shaft 1 6 are activated to drive the two fixed frames 17. The stirring frame 19 agitates the material inside the mixing drum 1, and combined with the heating of the heater 7, melts the material inside the mixing drum 1. After the material melts, the external PLC controller controls the servo motor 5 to reverse, causing the servo motor 5 and the rotating shaft 6 to drive the two fixed frames 17 and three scrapers 18 to scrape the inner wall of the mixing drum 1. Through the spiral arrangement of multiple stirring frames 19, the multiple stirring frames 19 can continuously convey the material adhering to the inner wall of the mixing drum 1 downwards. Then, the electrically controlled butterfly valve 4 is opened to allow the material inside the mixing drum 1 to enter the inner wall of the outer drum 21. Then, the servo motor 22 is started to drive the rotating shaft 23 to drive the spiral conveyor 24 and multiple protruding rods 25 to spirally convey the material entering the outer drum 21, and the multiple protruding rods 25 repeatedly agitate the material. Finally, the material is output from one end of the outer drum 21 and then conveyed to the external extruder for subsequent processing steps.
