[0002] Cellulose acetate butyrate (CAB) is an important organic compound mainly used in the production of high-transparency, weather-resistant plastic sheets, films, and leveling agents and film-forming substances for various coatings.

[0003] Currently, existing feeding devices for cellulose acetate butyrate production still have some drawbacks. They are often inconvenient to clean the inside of the device, and are generally fixed inside the storage tank. Long-term use can easily cause blockage inside the feeding pipe, affecting subsequent feeding efficiency. Therefore, we propose a feeding device for cellulose acetate butyrate production. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for the production of cellulose acetate butyrate, in order to solve the problem mentioned in the background art that it is inconvenient to clean the inside of the device, which is generally fixedly installed inside the storage box, and long-term use can easily cause blockage inside the feeding pipe, affecting the subsequent feeding efficiency.

[0006] Preferably, a groove is provided on both the front and rear sides of the discharge pipe, and a spring is provided inside the groove. One end of the spring is fixedly connected inside the groove, and the other end of the spring is fixedly connected to one side of the clamping block.

[0007] Preferably, the discharge pipe has a connecting pipe on the left side, the connecting pipe has an external thread on the outside, and the feed pipe has an internal thread on the right side, the external thread and the internal thread being compatible.

[0008] Preferably, a motor is provided on the left side of the feed pipe, and a rotating shaft is provided on the right side of the motor. The rotating shaft extends into the feed pipe and is rotatably connected to the inside of the feed pipe.

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

[0012] 1. Cellulose acetate butyrate is introduced into the feed pipe through the inlet, and then through the outlet pipe to the clamping pipe before entering the storage tank for production. After a period of use, the outlet pipe can be removed from the clamping pipe and taken out of the feed pipe to clean the inside of the feed pipe. This facilitates the cleaning of the inside of the feed pipe, avoids blockage, and improves the efficiency of subsequent feeding.

[0013] 2. By pressing the locking block, the spring extends and retracts, and the locking block enters the groove, separating the locking block from the groove. This facilitates the disassembly of the discharge pipe and the locking pipe. By starting the motor, the rotating shaft drives the stirring rod to rotate, stirring in real time. During stirring, the scraper scrapes to prevent acetic acid and butyric acid from adhering to the inner wall of the feed pipe, thereby improving the subsequent feeding effect.
