Description

Technical Field

[0001] This utility model relates to the technical field of thread protector extruders, and particularly to a quantitative weighing device for thread protector extruders. Background Technology

[0002] The extruder of the thread protector has a weighing barrel. By feeding a fixed amount of raw material into the weighing barrel, the raw material can be preheated by the heating element inside the weighing barrel. The molten raw material in the weighing barrel is mainly pushed into the extruder by the hydraulic cylinder. Since there is a heating plate on the weighing barrel, the heat generated is transferred to the hydraulic cylinder through the weighing barrel. The hydraulic cylinder will be damaged if it is heated for a long time. Therefore, this application provides a quantitative weighing device for the thread protector extruder that can cool down the hydraulic cylinder. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a quantitative weighing device for thread protector extruders, so as to solve the problem that the quantitative weighing device for thread protector extruders described in the background art lacks the function of cooling the hydraulic cylinder, resulting in a short service life of the hydraulic cylinder.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quantitative weighing device for a thread protector extruder, comprising... The weighing barrel body has a heating plate and a discharge pipe at the lower end that connects to the extruder; The upper end cover is located at the upper port of the weighing barrel body, and several feed holes are evenly arranged on the upper end cover. Several feed pipes are respectively set on the upper end cover at the corresponding feed pipe positions; Several heat insulation pads are arranged in a ring and fixedly connected to the upper end cover; A cooling box is set on several heat insulation pads. The cooling box has through holes, and the side wall of the cooling box has water outlet pipes and water inlet pipes that communicate with the cooling box. A hydraulic cylinder is installed on the upper wall of the cooling box, and the output end of the hydraulic cylinder slides through the through hole.

[0005] Preferably, the upper end cap is connected to the upper port of the weighing barrel body by a number of bolts.

[0006] Preferably, the heat insulation pad has a positioning hole that penetrates the heat insulation pad, and the cooling box has a screw that slides through the cooling box at the position corresponding to the positioning hole. The screw slides through the positioning hole and is threadedly connected to the upper end cover.

[0007] Preferably, the cooling box is a multi-prism shape, and several of the heat insulation pads are distributed at the corners of the cooling box.

[0008] The beneficial effects of adopting the above technical solutions are: This application, through the installation of heat insulation pads and cooling boxes, can separate the hydraulic cylinder from the weighing tank body, reducing heat transfer. At the same time, the inlet and outlet water pipes can inject circulating water into the cooling box, effectively removing heat energy and thus effectively improving the cooling effect on the hydraulic cylinder.

[0011] Figure 3 This is a schematic diagram of the heat insulation pad of this utility model.

[0012] The components include: weighing barrel body 10, discharge pipe 11, upper cover 20, bolt 21, electric heating plate 30, hydraulic cylinder 40, cooling box 50, through hole 51, water inlet pipe 52, water outlet pipe 53, heat insulation pad 60, screw 61, positioning hole 62, feed pipe 70, and feed hole 71. Detailed Implementation

[0013] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0014] like Figure 1-3 In this first embodiment, the thread protector extruder quantitative weighing device includes... The weighing barrel body 10 has a heating plate 30 and a discharge pipe 11 connected to an extruder at the lower end; The upper end cover 20 is located at the upper port of the weighing barrel body 10, and a plurality of feed holes 71 are evenly provided on the upper end cover 20. Several feed pipes 11 are respectively set on the upper end cover 20 at the positions corresponding to the feed pipes 70; Several heat insulation pads 60 are arranged in a ring and fixedly connected to the upper end cover 20; A cooling box 50 is disposed on several heat insulation pads 60. The cooling box 50 has a through hole 51, and the side wall of the cooling box 50 has a water outlet pipe 53 and a water inlet pipe 52 that communicate with the cooling box 50. A hydraulic cylinder 40 is installed on the upper wall of the cooling box 50, and the output end of the hydraulic cylinder 40 slides through the through hole 51.

[0015] This embodiment is implemented as follows: In use, room temperature water is injected into the cooling box 50 through the water inlet pipe 52, while the water outlet pipe 53 can discharge the heated water. The heat insulation pad 60 can isolate the cooling box 50 from the upper cover 20, which can effectively reduce the transfer of heat energy to the cooling box 50. This application mainly uses the cooling box 50 for cooling, which can effectively improve the service life of the hydraulic cylinder 40.

[0016] Please see Figure 1 The upper cover 20 is connected to the upper port of the weighing barrel body 10 by several bolts 21.

[0017] This application uses bolts 21 to connect the upper cover 20 to the weighing barrel body 10, which facilitates disassembly.

[0018] Please see Figure 1 , 2 3. The heat insulation pad 60 has a positioning hole 62 that penetrates the heat insulation pad 60. The cooling box 50 has a screw 61 that slides through the cooling box 50 at the position corresponding to the positioning hole 62. The screw 61 slides through the positioning hole 62 and is threadedly connected to the upper end cover 20.

[0019] This application uses a screw 61 to pass through the positioning hole 62 of the heat insulation pad 60 and connect to the upper end cover 20, thereby fixing the upper end cover 20, the heat insulation pad 60, and the cooling box 50; when the screw 61 passes through the cooling box 50, it avoids the cavity inside the cooling box 50.

[0020] Please see Figure 2 The cooling box 50 is a multi-faceted prism, with several heat insulation pads 60 distributed at the corners of the cooling box 50.

[0021] In this application, the cooling box 50 is configured as a multi-prism shape, and the heat insulation pads 60 are distributed at the corners, which can reduce heat transfer.

[0022] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
