Abstract

The invention provides a detaching device for a screw rod and a threaded element of an extruder, which comprises a frame bracket part, a screw rod sliding bracket part arranged on the frame bracket part, a heating ring sliding bracket part, a screw rod core shaft spline block-sleeve part, a jacking screw rod part and a uniform-temperature heating ring part arranged on the heating ring sliding bracket part. The uniform-temperature heating ring part arranged on the detaching device is used for uniformly heating the screw rod and a threaded block of the extruder, thereby conveniently and stably controlling temperature, protecting technical property of the threaded element, and prolonging the service life of the threaded element. The arranged jacking screw rod part and screw rod core shaft spline block-sleeve part can be used for preventing the screw rod from moving back and forth and rotating during detaching the screw rod, thereby fixing the screw rod and conveniently heating and detaching. By using a metal square tube, the casting cost is saved. The structure is simple and the operation is convenient.

Description

technical field [0001] The invention relates to a component removal device used in the production of chemical plastics, in particular to a screw thread component removal device of an extruder. Background technique [0002] At present, it is often necessary to change the combination of screw thread blocks in the screw extruder. The existing methods for removing the thread blocks on the screw mandrel include: 1. Heat the thread blocks one by one with fire until the feed material melts and is easy to remove; 2. Use Dedicated dismantling screw thread block dismantling machine, etc. [0003] Its disadvantages are: [0004] 1. The operation of burning the screw mandrel of the existing equipment is not safe, and the temperature is not suitable for control; [0005] 2. Existing equipment fire-burned thread block is easy to burn the thread block or cause the process performance of the thread block to change and become fragile and not durable; [0006] 3. It is time-consuming, labo...
