Description

Technical Field

[0001] This utility model relates to the field of resin particle feeding, specifically a feeding device for the production of insulating resin tubes. Background Technology

[0002] When resin is used to make pipes, it needs to go through the processes of feeding, mixing, molding and cooling.

In this case, the unused raw material needs to be discharged. In the existing technology, the raw material is generally discharged by changing the outlet position. After discharge, the operator needs to reset the pipe outlet again. In the above process, the height of the outlet is located at a high position, which is inconvenient to operate and is prone to causing the discharged material to spill. Utility Model Content

[0017] 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.

[0018] Please see Figures 1-4In this embodiment of the present invention, a feeding device for producing insulating resin tubes includes a feeding hopper 1. The discharge pipe at the bottom of the feeding hopper 1 is connected to the feeding pipe of a first fixed pipe 2 via a flange. A rotating pipe 3 is rotatably installed at one end of the feeding pipe of the first fixed pipe 2. A second fixed pipe 4 is rotatably installed at one end of the rotating pipe 3. The end of the second fixed pipe 4 away from the rotating pipe 3 is connected to a feeding tank connected to a resin melting device. A discharge mechanism is formed on the outer periphery of the rotating pipe 3. Drive mechanisms are distributed and installed on the outer periphery of the first fixed pipe 2 and the outer periphery of the rotating pipe 3. A feeding mechanism is installed at the tail end of the first fixed pipe 2, penetrating the first fixed pipe 2 and the rotating pipe 3, and extending into the interior of the second fixed pipe 4.

[0019] In this embodiment: First, the bagged resin granules are poured into the feed hopper 1 and the feeding mechanism is started. The granular resin raw material enters the interior of the first fixed pipe 2 through the discharge pipe and the feed pipe. The running feeding mechanism conveys the resin granules upward to the feed pipe of the resin melting equipment (resin melting equipment: twin screw extruder). The resin granules move through the first fixed pipe 2, the rotating pipe 3, and the second fixed pipe 4.

[0020] After production is completed, the raw materials located in the No. 1 fixed pipe 2, rotating pipe 3, No. 2 fixed pipe 4 and feed hopper 1 need to be discharged. At this time, by starting the drive mechanism, the drive mechanism drives the rotating pipe 3 to rotate 180 degrees. At this time, the rotating pipe 3 drives the discharge pipe 6 to rotate from the top to the bottom. Then, by opening the discharge mechanism, the resin particles in the feed hopper 1, No. 1 fixed pipe 2, rotating pipe 3 and No. 2 fixed pipe 4 can be discharged without adjusting the discharge position of No. 2 fixed pipe 4.

[0021] Please refer to this carefully. Figure 1 and Figure 2 The discharge mechanism includes a discharge pipe 6 integrally formed on the outer periphery of the rotating pipe 3. A connecting cover 7 is threadedly connected to the outer wall of the discharge port of the discharge pipe 6, and a handle 8 is fixedly installed on the outer wall of the connecting cover 7.

[0022] In this embodiment: before discharging, the feeding mechanism is turned off, and then the drive mechanism is started. The drive mechanism drives the rotating pipe 3 to rotate 180 degrees. The rotating pipe 3 drives the discharge pipe 6 to rotate from top to bottom. Then, the connecting cover 7 is rotated and opened by the handle 8, and the feeding mechanism is started again. At this time, the raw material can be discharged outward through the discharge pipe 6. After the discharge is completed, the drive mechanism is started again to drive the discharge pipe 6 to rotate upward, so as to avoid resin raw material particles getting stuck in the discharge pipe 6 during the next use.

[0023] Please refer to this carefully. Figure 1 and Figure 2The drive mechanism includes a mounting bracket 9 fixedly installed on the outer periphery of the first fixed pipe 2. A drive motor 10 is fixedly installed in the mounting opening below the mounting bracket 9. A drive gear 11 is fixedly installed at the output end of the drive motor 10. The drive mechanism also includes a driven gear 12 interference-fitted on the outer periphery of the rotating pipe 3. The driven gear 12 has the same size as the drive gear 11. The tooth blocks on the outer periphery of the drive gear 11 are distributed at ninety degrees.

[0024] In this embodiment: by starting the drive motor 10, the drive motor 10 drives the drive gear 11 to rotate. During the rotation, the drive gear 11 gradually meshes with the driven gear 12. After the two mesh, the driven gear 12 rotates until the two separate again. Since the drive gear 11 is a half gear structure, it can achieve the purpose of driving the rotating pipe 3 and the discharge pipe 6 to rotate 180 degrees in a single rotation.

[0025] Please refer to this carefully. Figure 3 and Figure 4 The ends of the first fixed pipe 2 and the second fixed pipe 4 that connect with the rotating pipe 3 are integrally formed with outwardly protruding connecting rings 14. The two ends of the rotating pipe 3 are provided with rotating grooves that match the connecting rings 14. Friction damping is provided at the position where the rotating grooves and the connecting rings 14 are connected.

[0026] In this embodiment: when the rotating pipe 3 rotates, the rotating pipe 3 drives the rotating groove to rotate around the outer periphery of the connecting ring 14. When the rotating pipe 3 stops rotating, the rubber friction damper can provide effective friction force to prevent the rotating pipe 3 and the discharge pipe 6 from rotating on their own.

[0027] Please refer to this carefully. Figure 4 The feeding mechanism includes a feeding motor 5 installed at the tail end of the first fixed pipe 2. The output end of the feeding motor 5 is coaxially fixedly connected to a spiral conveying rod 13, which is located in the inner cavity of the first fixed pipe 2, the rotating pipe 3, and the second fixed pipe 4.

[0028] In this embodiment: During the feeding process, the feeding motor 5 is started, and the feeding motor 5 drives the spiral conveyor rod 13 to rotate. At this time, the spiral part of the spiral conveyor rod 13 can push the resin particle raw material upward during the rotation.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
