Description

Technical Field

[0001] This utility model relates to the field of discharge valve core technology, specifically a disassembly tool for discharge valve cores used in extruders. Background Technology

[0002] The discharge valve core is a component used to control the movement of materials. It is usually located in the center of the extruder's discharge valve and controls the material's movement by rotating or moving it. The discharge valve core plays a crucial role in the extruder's discharge valve, ensuring that materials can be discharged smoothly.

[0003] The discharge valve core needs to be disassembled from the discharge valve regularly for maintenance or replacement. Currently, when separating the discharge valve core, a hammer is usually used to strike the discharge valve core and pull it off the valve. This can easily damage the valve body, reduce its service life, and the operation is cumbersome, requiring workers to constantly use a hammer to strike it, wasting a lot of their physical strength and taking a long time. Utility Model Content

[0004] The purpose of this utility model is to provide a disassembly tool for the discharge valve core of an extruder. It has the advantages of simple structure and reasonable design, which can easily and quickly remove the valve core, save working time, avoid consuming a lot of physical strength of workers, and avoid damage to the valve body. The disassembly process is very simple, which solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disassembly tool for a discharge valve core of an extruder, comprising a disassembly assembly disposed on the valve core, and the disassembly assembly including a support sleeve and a fixing plate fixed on the support sleeve. A bearing is disposed on the fixing plate, and a lead screw is installed in the bearing. The lead screw passes through the fixing plate from top to bottom and extends into the valve core. The valve core includes a core seat body and a protrusion disposed on the top of the core seat body. The core seat body is disposed in the valve body, wherein the bottom of the lead screw is fixed in the protrusion, so that the protrusion and the core seat body can be lifted upward when the lead screw is running.

[0006] Preferably, the fixed plate, bearing, and lead screw are all coaxially designed, and a nut is installed on the bearing; the nut is used to fix the bearing to the fixed plate.

[0007] Preferably, the lead screw is set vertically, and a handle is fixed to the top of the lead screw; the lead screw can be rotated by the handle.

[0008] Preferably, a limiting hole is formed on the upper end face of the protrusion, and the lead screw is inserted into the limiting hole from top to bottom and fixed to the protrusion; when the lead screw is rotated, it can drive the protrusion to move upward.

[0009] Preferably, the valve core is disposed on the unloading valve, wherein the unloading valve includes a valve body and a positioning groove is provided on the top of the outer circle of the valve body.

[0010] Preferably, the support sleeve is inserted into the positioning groove in the vertical direction and abuts against the valve body. The support sleeve can maintain the stability of its own structure with the help of the valve body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model provides a disassembly tool for a discharge valve core used in an extruder. The disassembly tool includes a disassembly assembly disposed on the valve core. The disassembly assembly includes a support sleeve and a fixing plate fixed to the support sleeve. A bearing is disposed on the fixing plate, and a lead screw is installed in the bearing. The lead screw passes through the fixing plate from top to bottom and extends into the valve core. The valve core includes a core seat body and a protrusion disposed on the top of the core seat body. The core seat body is disposed in the valve body, and the bottom of the lead screw is fixed in the protrusion. By rotating the lead screw, the protrusion and the core seat body can be lifted upward. This disassembly tool for a discharge valve core used in an extruder has a simple structure and reasonable design. By rotating the lead screw on the bearing, the valve core can be lifted upward as a whole, and the valve core can be pulled out vertically from the discharge valve. This allows the valve core to be easily and quickly removed, saving working time and avoiding a lot of physical labor for workers, as well as preventing damage to the valve body.

[0013] 2. The disassembly tool for the discharge valve core of an extruder provided by this utility model only requires the support sleeve to be abutted against the positioning groove, and then the handle is used to drive the screw to rotate, so that the valve core can be automatically removed from the discharge valve. The method of use and the process of disassembling the valve core are very simple. Therefore, the disassembly tool for the discharge valve core of an extruder is highly practical.

[0023] Please see Figure 2 The disassembly assembly 3 includes a support sleeve 31 and a fixed plate 32 fixed on the support sleeve 31. A bearing 33 is provided on the fixed plate 32, and a lead screw 35 is installed in the bearing 33. The lead screw 35 passes through the fixed plate 32 from top to bottom and extends into the valve core 2. The lead screw 35 is vertically arranged. The fixed plate 32, the bearing 33 and the lead screw 35 are all coaxially designed. A nut 34 is installed on the bearing 33. The nut 34 is used to fix the bearing 33 to the fixed plate 32. A handle 36 is fixed to the top of the lead screw 35. The lead screw 35 can be rotated by the handle 36.

[0024] Please see Figure 3 The valve core 2 includes a core seat body 21 and a protrusion 22 disposed on the top of the core seat body 21. The core seat body 21 is disposed inside the valve body 11. The installation method between the core seat body 21 and the valve body 11 is the prior art.

[0025] Please see Figure 4 The bottom of the lead screw 35 is fixed inside the protrusion 22. A limiting hole 23 is formed on the upper end face of the protrusion 22. The lead screw 35 is inserted into the limiting hole 23 from top to bottom and fixed to the protrusion 22. When the lead screw 35 is running, it can drive the protrusion 22 to move upward. Therefore, when the lead screw 35 is running, the protrusion 22 and the core seat body 21 can be lifted upward. The unloading valve 1 includes a valve body 11. A positioning groove 12 is provided on the top of the outer circle of the valve body 11. The structure of the unloading valve 1 and the valve core 2 is the prior art and will not be described in detail here.
