Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Reference Figs. 1-3 A temperature control device for the die lip of a transparent sheet extruder includes an extrusion cylinder 1. An extrusion head 2 is fixed and connected to the end face of the extrusion cylinder 1. Two slide plates 5 are symmetrically slidably connected to the outer side of the extrusion head 2. The extrusion head 2 drives the two slide plates 5 to slide symmetrically through a drive mechanism. Multiple heating rods 10 are symmetrically installed inside each slide plate 5. A water inlet pipe 8 and a water outlet pipe 9 are fixed and connected to the outer side of each slide plate 5. A cleaning plate 14 is slidably connected to the side of each slide plate 5, and each cleaning plate 14 abuts against the side of the slide plate 5 at the corresponding position. The slide plate 5 drives each cleaning plate 14 to slide through a transmission mechanism.
[0022] The drive mechanism moves the two slide plates 5 closer or further apart, allowing the die lip to extrude sheets of different thicknesses. Simultaneously, multiple heating rods 10 can uniformly heat the slide plates 5. Water can be injected into the slide plates 5 through the inlet pipe 8 and outlet pipe 9, and heated by the heating rods 10, thus maintaining the uniformity of heating of the slide plates 5. When it is necessary to cool the slide plates 5, cooling water can be injected through the inlet pipe 8 and hot water can be discharged through the outlet pipe 9, thereby achieving the temperature control effect of the slide plates 5. Furthermore, the cleaning plate 14 can clean the residual material on the outside of the slide plates 5, evenly pushing the material to the other side to prevent residual material from affecting the normal use of the die lip.
[0023] A mounting base 16 is provided between the two slide plates 5. Push rods 19 are slidably connected to both ends of the mounting base 16, and the other end of each push rod 19 is fixedly connected to the corresponding cleaning plate 14. A movable seat 17 is fixedly installed at the end of each push rod 19 away from the cleaning plate 14, and each movable seat 17 is slidably connected inside the mounting base 16. A spring 18 is installed between each movable seat 17 and the side wall of the mounting base 16. Through the force of the two springs 18, each push rod 19 can drive the cleaning plate 14 to abut against the side of the slide plate 5, thereby making the slide plate 5 more thoroughly cleaned.
[0024] The transmission mechanism includes a threaded rod 12, which is rotatably connected to one of the slide plates 5. A second motor 13 is fixedly installed on the outer side of the corresponding slide plate 5, and the output shaft of the second motor 13 is connected to the threaded rod 12. A threaded seat 15 is fixedly installed on the outer side of each cleaning plate 14, and the corresponding threaded seat 15 is threadedly connected to the threaded rod 12.
[0025] The drive mechanism includes two L-shaped plates 3, which are fixedly installed on the top and bottom surfaces of the extrusion head 2, respectively. The two L-shaped plates 3 are rotatably connected to a bidirectional screw 6, and two slide plates 5 are symmetrically threaded onto the bidirectional screw 6. A first motor 4 is fixedly installed on the top surface of one of the L-shaped plates 3, and the output shaft of the first motor 4 is connected to the bidirectional screw 6.
[0026] Each slide plate 5 has a groove 11 on its outer side, and each threaded seat 15 is slidably connected to the groove 11 corresponding to its position. The groove 11 guides and limits the threaded seat 15 to prevent it from rotating.
[0027] Two L-shaped plates 3 are jointly equipped with a limit rod 7, and each slide plate 5 is slidably connected to the limit rod 7. The limit rod 7 limits the slide plate 5, preventing it from rotating.
[0028] When this utility model is in use, the first motor 4 can be started to drive the bidirectional screw 6 to rotate. With the cooperation of the limiting rod 7, the two slide plates 5 can be brought closer to each other, thereby adjusting the thickness of the extruded sheet material by the die lip. At the same time, the water source inside the slide plate 5 can be heated by starting multiple heating rods 10 inside each slide plate 5. The slide plate 5 is heated evenly through the heat conduction of the water source. Hot water can be discharged and cooling water can be delivered into the slide plate 5 through the cooperation of the water inlet pipe 8 and the water outlet pipe 9, thereby facilitating the temperature control of the slide plate 5.
[0029] Meanwhile, after the sheet is extruded and formed, the threaded rod 12 can be rotated by starting the second motor 13. Under the limit of the slide groove 11, since the two cleaning plates 14 are connected to the assembly seat 16 and other components through the push rod 19, each cleaning plate 14 can be driven to slide. At the same time, through the cooperation of the spring 18 in the assembly seat 16 and the moving seat 17, the cleaning plate 14 can be driven by the push rod 19 to always abut against the side of the slide plate 5 when the cleaning plate 14 slides, so as to facilitate the thorough cleaning of the side of the slide plate 5 and quickly push the residual material to the other side so as not to affect the normal extrusion of the die lip. Then, the material adhering to the cleaning plate 14 can be removed manually or mechanically.
[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
