[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Example
[0018] like Figure 1-3As shown, a polyester fiber chip spinning device proposed by the utility model comprises a screw extruder 2, a molding box 3 and a pressure stabilizing frame 4, the screw extruder 2 is fixed on the equipment base 1, the pressure stabilizing frame 4 is fixed at the upper center position of the molding box 3, and the bottom is located in the molding box 3, a molding disk 5 is fixed at the bottom of the pressure stabilizing frame 4, and molding holes 51 are evenly opened on the molding disk 5, the end of the screw extruder 2 is fixed to the side wall of the pressure stabilizing frame 4, a feed port 22 is opened on the side wall of the pressure stabilizing frame 4 and at the connection with the screw extruder 2, a piston plate 41 is slidably connected in the pressure stabilizing frame 4, a control panel is fixed on the equipment base 1, a hopper 21 is fixed at the front end of the screw extruder 2, a sieve plate 23 is fixed on the side of the screw extruder 2 close to the feed port 22, a check valve is installed in the feed port 22, a pressure sensor 43 is fixed to the inner wall of the bottom of the pressure stabilizing frame 4, a telescopic cylinder 42 is fixed on the upper end of the pressure stabilizing frame 4, and the output of the telescopic cylinder 42 is fixed on the piston plate 41.
[0019] A collecting plate 32 is fixed in the middle position of the forming box 3, and a funnel hole is set in the center of the collecting plate 32. A winding disk 33 is rotatably connected inside the forming box 3 and located below the collecting plate 32. A winding motor 34 is fixed to the outer wall of the forming box 3 to drive the winding disk 33 to rotate. The front and rear side walls of the forming box 3 and located above the collecting plate 32 are open structures. Heat sinks 31 are fixed on both sides of the forming box 3 and located above the collecting plate 32. The heat sink 31 can be used to increase the heat dissipation speed in the forming box 3, thereby making the spinning forming speed faster.
[0020] In this embodiment, the entire device is first connected to an external power supply, and then the raw material slices are placed in the hopper 21, heated and melted by the screw extruder 2, and extruded, so that the hot-melt material enters the voltage stabilizing frame 4. During this process, the telescopic cylinder 42 can be used to drive the piston plate 41 to move up and down. When moving downward, the hot-melt material can be squeezed to increase its extrusion pressure. Conversely, when the internal pressure is too large, the piston plate 41 can be driven to move upward to keep its extrusion pressure stable. During this process, the pressure sensor 43 can be used to monitor the pressure value of the hot-melt material. When extruding at a constant pressure, the hot-melt material can stably pass through the forming hole 51 to form a stable filament. After falling and contacting with the air for cooling, it can be quickly formed. The final formed filament passes through the collecting plate 32 and is wound and stored on the winding disk 33. During the whole process, the stable extrusion pressure ensures the quality of the spinning product. At the same time, the screening of the sieve plate 23 can block the slice particles that have not melted in time, thereby reducing the risk of clogging the forming hole 51.
[0021] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
