[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a polymerization reaction device includes: a polymerization chamber 20, which is a hollow cylindrical shape with a feed inlet at the top of the polymerization chamber 20; a motor 22 is fixedly connected to the top of the polymerization chamber 20; a stirring shaft 23 is rotatably connected inside the polymerization chamber 20; the motor 22 can drive the stirring shaft 23 to rotate; and a stirring plate 24 is fixedly connected to the wall of the stirring shaft 23.

[0030] The observation chamber 21 is a hollow cylindrical shape. The top of the observation chamber 21 can be fixedly connected to the bottom of the polymerization chamber 20. The observation chamber 21 is made of transparent material. A solenoid valve is installed at the connection between the observation chamber 21 and the polymerization chamber 20. A solenoid valve is also installed at the bottom of the observation chamber 21. The motor 22 is electrically connected to the corresponding power supply. This is existing technology, so it will not be described in detail here.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an agitation structure is installed inside the observation chamber 21 to agitate the cooled polycaprolactone within the chamber. The agitation structure includes a rotating ring 32, a connecting plate 33, and a lever 34. The rotating ring 32 is rotatably connected to the top of the observation chamber 21, the connecting plate 33 is fixedly connected to the wall of the rotating ring 32, and the lever 34 is fixedly connected to the bottom of the connecting plate 33. The rotating ring 32 can rotate within the observation chamber 21.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the rotating ring 32 is circular, and the connecting plate 33 is triangular. The connecting plate 33 is symmetrically arranged on the inner arc surface of the rotating ring 32. Each connecting plate 33 has a corresponding rectangular deflector plate 34 at its bottom. The agitation structure also includes a base frame 30 and a fixed plate 31. The base frame 30 is fixedly connected to the top of the observation chamber 21 and is a circular ring with a U-shaped cross-section. The rotating ring 32 is rotatably connected to the opening of the base frame 30. The fixed plate 31 is fixedly connected to the outer wall of the base frame 30. A rectangular opening is provided at the position of the fixed plate 31 on the top of the base frame 30. The agitation structure also includes... It includes a driven ring 35, a driving column 36, and a force transmission belt 37. The driven ring 35 is fixedly connected between symmetrical connecting plates 33. The driving column 36 is rotatably connected to the top of the fixed plate 31. The force transmission belt 37 is sleeved on the wall surface of the driven ring 35 and the driving column 36. The driven ring 35 is annular. The cavity of the driven ring 35 can be the same size as the solenoid valve at the top of the observation chamber 21. The driven ring 35 is located at the center of the top of the observation chamber 21. The driving column 36 is cylindrical. The force transmission belt 37 is located in the rectangular opening at the top of the base frame 30. The force transmission belt 37 can transmit power between the driven ring 35 and the driving column 36.

[0033] In practical use, the polycaprolactone to be polymerized and other materials are added into the chamber of polymerization chamber 20 through the feed inlet at the top of the chamber. Then, the power to the motor 22 is turned on, and the motor 22 drives the stirring shaft 23 to rotate. As the stirring shaft 23 rotates, it drives the stirring plate 24 to stir and polymerize the materials in the chamber of polymerization chamber 20. After polymerization is completed, the solenoid valve at the top of the observation chamber 21 is opened. The polymerized polycaprolactone will flow downward from the solenoid valve, pass through the driven ring 35, and accumulate in the chamber of observation chamber 21. At this time, the polymerized polycaprolactone in the chamber of observation chamber 21 can be observed through the observation chamber 21. When the active column 36 is rotated, it can drive the driven ring 35 to rotate through the force transmission belt 37. As the driven ring 35 rotates, it can drive the connecting plate 33, the dial plate 34 and the rotating ring 32 to rotate synchronously. The rotating ring 32 can rotate within the cavity of the base frame 30, while the dial plate 34 can agitate the polycaprolactone that has completed polymerization in the observation chamber 21 when it rotates. Thus, the degree of polymerization of all polycaprolactone can be observed through the observation chamber 21. When the observation is completed and the required degree of polymerization is confirmed, the solenoid valve at the bottom of the observation chamber 21 is opened, and the polycaprolactone that has polymerized in the observation chamber 21 can be discharged from the solenoid valve at the bottom.

[0034] In summary, by setting up a stirring structure, the polycaprolactone that has completed polymerization can be manually stirred when observing it. The stirring structure drives the baffle 34 in the observation chamber 21 to stir the polycaprolactone in the observation chamber 21 by rotating the active column 36. This allows the observer to observe the specific polymerization status of the polycaprolactone in the observation chamber 21 through the observation chamber 21, thereby obtaining a more accurate degree of polymerization of polycaprolactone.

[0035] like Figure 2 and Figure 3 As shown, an upper guide ring 25 is fixedly connected to the bottom of the cavity of the polymerization chamber 20. The upper guide ring 25 is a circular ring with a right-angled triangular cross section. The opening size at the center of the upper guide ring 25 is the same as the size of the solenoid valve at the top of the observation chamber 21. A lower guide ring 27 is fixedly connected to the bottom of the cavity of the observation chamber 21. The lower guide ring 27 is a circular ring with a right-angled triangular cross section. The opening size at the center of the lower guide ring 27 is the same as the size of the solenoid valve at the bottom of the observation chamber 21.

[0036] In practical use, the polycaprolactone in the polymerization chamber 20 can move along the inclined surface of the upper guide ring 25 toward the solenoid valve at the top of the observation chamber 21, and the lower guide ring 27 can guide the polycaprolactone in the observation chamber 21 toward the bottom of the observation chamber 21.

[0037] In summary, by setting the upper guide ring 25 and the lower guide ring 27, the movement speed of polycaprolactone in the polymerization chamber 20 and the observation chamber 21 can be effectively increased, and all polycaprolactone can be accurately passed through the corresponding solenoid valve.

[0038] Working principle: The polycaprolactone to be polymerized and other materials are added into the chamber of polymerization chamber 20 through the feed inlet at the top of the chamber. Then, the power to the motor 22 is turned on, and the motor 22 drives the stirring shaft 23 to rotate. As the stirring shaft 23 rotates, it drives the stirring plate 24 to stir and polymerize the materials in the chamber of polymerization chamber 20. After polymerization is completed, the solenoid valve at the top of the observation chamber 21 is opened. The polymerized polycaprolactone will flow downward from the solenoid valve, pass through the driven ring 35, and accumulate in the chamber of observation chamber 21. At this time, the polymerized polycaprolactone in the chamber of observation chamber 21 can be observed through the observation chamber 21. When the active column 36 is rotated, it can drive the driven ring 35 to rotate through the force transmission belt 37. As the driven ring 35 rotates, it can drive the connecting plate 33, the agitator plate 34 and the rotating ring 32 to rotate synchronously. The rotating ring 32 can rotate within the cavity of the base frame 30, while the agitator plate 34 can agitate the polycaprolactone that has completed polymerization in the observation chamber 21 when it rotates. Thus, the degree of polymerization of all polycaprolactone can be observed through the observation chamber 21. When the observation is completed and the required degree of polymerization is confirmed, the solenoid valve at the bottom of the observation chamber 21 is opened, and the polycaprolactone that has polymerized in the observation chamber 21 can be discharged from the solenoid valve at the bottom.
