[0021] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1: A large-flow discharge device that is easy to clean is installed at the bottom of the reactor 1, mainly used for discharging materials, and is also easy to clean to reduce the probability of the material staying on the wall. The reactor 1 has a discharge port 1-1, and the discharge device is sealed and connected to the discharge port 1-1 to ensure discharge while reducing the probability of material leakage. In order to simplify the structure of the melt flow channel and facilitate its cleaning, the present embodiment is configured to include a discharge mechanism and a diversion mechanism. Specifically, the discharge mechanism includes a ball valve upper body 2, a ball valve lower body 4, a discharge ball 5 having a discharge channel 5-1 therein, and a valve stem 3 for changing the size of the discharge port 1-1 by driving the discharge ball 5 to rotate. The ball valve upper body 2 is sealedly connected to the bottom of the reactor 1, that is, the discharge device is sealedly connected to the discharge port 1-1. The ball valve lower body 4 is connected to the ball valve upper body 2 and a cavity 5-2 is formed inside the two for installing the discharge ball 5. The ball valve upper body 2 and the ball valve lower body 4 are detachable structures. On the one hand, it is convenient to install the discharge ball 5 in the cavity 5-2 formed by the two. On the other hand, it is convenient to clean the cavity 5-2 and ensure the cleaning effect. The valve stem 3 is installed on the side of the discharge ball 5 and partially extends outside the cavity 5-2, so as to facilitate the operation of the discharge ball 5, that is, the switch of the discharge ball 5 is controlled by the valve stem 3. Specifically, the discharge ball 5 is pushed by the valve stem 3 to change the size of the discharge port 1-1, thereby changing the discharge rate and amount of the material. In order to further ensure the sealing performance, a valve seat seal 10 is arranged between the upper body 2 of the ball valve and the lower body 4 of the ball valve. The valve seat seal 10 is a sealing ring structure. The upper body 2 of the ball valve and the lower body 4 of the ball valve are both installed with valve seat seals 10. The pressure between the discharge ball 5 and the valve seat seal 10 is controlled by the tightness of the locking member 30 on the flange at the connection between the upper body 2 of the ball valve and the lower body 4 of the ball valve. The locking member 30 is a locking bolt with a simple structure and convenient connection. A gasket is also placed between the flanges to further achieve sealing.

[0025] The above-mentioned diversion mechanism includes a diverter head shell 6 and a diverter head. The above-mentioned diverter head shell 6 is outward-expanding from top to bottom as a whole. The inner wall of the outward-expanding structure is a smooth wall surface without a tortuous structure, which helps to reduce the contact area between the material strip 28 and the inner wall of the diverter head shell 6 under high temperature conditions and reduce the possibility of adhesion. Especially when working under high temperature conditions, the outward-expanding structure can reduce the adhesion of the material strip 28 and the diverter head shell 6, thereby reducing the probability of the material body adhering to the inner wall of the diverter head shell 6, so as to facilitate its later cleaning and ensure the cleaning effect. The outward-expanding design can also make the flow of the molten material smoothly transition from rotational motion to linear motion, thereby ensuring the uniformity of the plastic melt during extrusion. A melt flow channel 6-1 is formed inside the above-mentioned diverter head shell 6. Similarly, the melt flow channel 6-1 is outward-expanding from top to bottom. When discharging, the central axis of the above-mentioned discharge channel 5-1 can be located on the same straight line as the central axis of the above-mentioned melt flow channel 6-1, thereby ensuring the discharge efficiency. The above-mentioned diverter head shell 6 is installed at the bottom of the above-mentioned ball valve lower body 4 and is connected. The above-mentioned diverter head, i.e., the casting belt head, has multiple casting belt holes and is installed in the above-mentioned melt flow channel 6-1. The main function of the diverter head is to extrude and distribute the polymer in the molten state and form a strand belt. The above-mentioned diverter head and the above-mentioned diverter head shell 6 and the above-mentioned diverter head shell 6 and the above-mentioned discharging mechanism also have heating elements for heating the material to ensure the fluidity of the logistics during discharging and the material will not solidify during cleaning. The heating element can be a heating plate or a heating wire or other structure, which is mainly used to heat the material body to ensure that the material body flows evenly in the diverter head and the diverter head shell to avoid uneven flow caused by uneven temperature. The material body, especially the plastic melt, needs to maintain a certain temperature during the extrusion process to ensure its fluidity and plasticizing effect. The heating element can provide continuous external heat to heat the polymer melt from a solid state to a molten state, maintain a suitable processing temperature, and thus ensure the subsequent production quality. The heating element can also be electric heating, steam or thermal oil heating. In order to further ensure the temperature stability, a heat preservation device may be provided at the discharging mechanism and the diversion mechanism. The heat preservation device may be heat preservation cotton, heat preservation cover or other devices that can meet the heat preservation requirements.

[0026] The upper part of the above-mentioned splitter housing 6 is connected to the above-mentioned ball valve lower body 4 through a flange and a connecting bolt, and a sealing gasket is arranged in the middle of the flange. The above-mentioned splitter housing 6 is connected to the above-mentioned splitter by a connecting thread 7. Specifically, the bottom of the above-mentioned splitter housing 6 has an internal thread, and the above-mentioned splitter has an external thread matched with the above-mentioned internal thread. The above-mentioned splitter and the above-mentioned splitter housing 6 are connected by a thread, which is convenient for frequent disassembly and cleaning.

[0027] like Figure 8As shown, the bottom of the above-mentioned diverter head is provided with a robot arm connecting shaft 13 for connecting with the docking seat 35 on the robot arm 33, the docking seat 35 is placed on the robot arm 33, and the robot arm 33 is placed on the robot arm guide rail 34. The above-mentioned robot arm 33 is connected to the above-mentioned robot arm connecting shaft 13 to drive the above-mentioned diverter head to rise and fall. The wall surface of the above-mentioned robot arm connecting shaft 13 is provided with a torsion bar socket 14 for the torsion bar to be inserted. The robot arm 33 lowers the diverter head to separate the diverter head from the diverter head housing 6, that is, the diverter head and the melt flow channel 6-1 can be cleaned thoroughly to ensure that there is no residual material.

Specifically, the above-mentioned double-layer cast belt head type diverter head 11 includes an upper cast belt head 15 and a lower cast belt head 16. The upper cast belt head 15 has an upper cast belt hole 8, and the lower cast belt head 16 has a lower cast belt hole 9. A melt diverter ring 12 is provided below the double-layer cast belt head type diverter head 11. The upper cast belt hole 8 is located on the outer circle of the melt diverter ring 12, and the lower cast belt hole 9 is located on the inner circle of the melt diverter ring 12. The casting belt holes are circumferentially arranged on the upper casting belt head 15 and the lower casting belt head 16, and the number of casting belt holes is set according to the area size of the upper casting belt head 15 and the lower casting belt head 16. According to the material properties and the material cooling method, the inner and outer rings of the same casting belt holes can be arranged in a staggered or close arrangement, or only one ring of casting belt holes can be set, which can reduce the adhesion of different liquid crystal polymer material strips 28 during pelletizing. The melt diverter ring 12 determines the position of its peak according to the number of casting belt holes of the upper casting belt head 15 and the lower casting belt head 16, ensuring that the melt is evenly distributed to all the casting belt holes of the upper casting belt head 15 and the lower casting belt head 16.

A plurality of the feed water flow pipes 19 are respectively installed in the upper water tank feed tray 17 and the lower water tank feed tray 18, a plurality of the spray water pipes 20 are installed on the top of the upper water tank 25 and the lower water tank 26, the upper water tank 25 and the lower water tank 26 are installed along the height direction of the support frame 27, the upper water tank nip roller 21 is installed at the outlet of the upper water tank 25, the material strips 28 are located between the upper water tank nip roller 21 and the upper water tank feed roller 22 and then transferred to the lower water tank nip roller 23 located in the lower water tank 26, and the material strips 28 are finally cut at the pelletizer 24. The pelletizer 24 can also be connected to a dryer, a vibrating screen, a silo, etc.

[0030] The number of the upper water tank material guide plate 17 and the lower water tank material guide plate 18 can be set as needed, and they are distributed in a ring shape, that is, the material is cut from multiple directions to increase the material discharge rate. In this embodiment, at least two single-layer or multi-layer water tanks with telescopic material guide plates are formed, preferably four double-layer water tanks, and the water tanks can surround a circle and respectively connect the material strips 28 of the upper casting strip head 15 and the lower casting strip head 16.

[0031] When the feed tray on the water trough retracts, the robot arm 33 can lower the diverter head to below the height of the water trough for cleaning. When the feed tray on the water trough extends, it can catch the material strip 28 flowing out of the casting strip head. The upper water trough feed tray 17 and the lower water trough feed tray 18 can be installed on the sliding guide rail 29 respectively, and sliders are installed at the bottom of the upper water trough feed tray 17 and the lower water trough feed tray 18 respectively.
