DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] The high-frequency melt extrusion equipment for processing plastic products disclosed in the present invention is mainly applied to the existing high-frequency melt extrusion equipment during use. When the molten raw materials are initially input, the molten material gradually moves to the extrusion plate. The molten material that initially arrives is at the lower position of the extrusion tube and cannot cover the various extrusion holes of the extrusion plate. This will cause the shape of the plastic that initially passes through the extrusion plate to be irregular, which will cause the loss of the molten raw materials.

[0032] Reference Figure 1-Figure 10A high-frequency melt extrusion device for processing plastic products, comprising a placement seat 1, the top of the placement seat 1 is fixedly connected with an extrusion channel 8, and one end of the extrusion channel 8 is fixedly connected with an extrusion plate 6, the placement seat 1 is located at the other end of the extrusion channel 8 and is fixedly connected with a drive motor 2, the output shaft of the drive motor 2 is fixedly connected with a conveying shaft 10 through a coupling, the outer side wall of the conveying shaft 10 is fixedly connected with a spiral conveying blade 9, the inner walls of both sides of the extrusion channel 8 near the extrusion plate 6 are provided with mounting grooves 11, and the two mounting grooves 11 are fixedly connected with the outer side wall of the extrusion channel 8. A centralized passing module 12 is provided inside, and the centralized passing module 12 includes two centralized baffles 1201, which are connected to the inner walls on both sides of the extrusion channel 8 through hinges, and the two centralized baffles 1201 are in contact with each other. A fixed groove 1216 is opened on the same side of the two centralized baffles 1201, and the inner wall of the fixed groove 1216 is fixedly connected with pressure sensors 1214 at equal distances, and the inner wall of the fixed groove 1216 located between every two pressure sensors 1214 is fixedly connected with a filling rod 1202.

[0033] In a specific application scenario, in the process of gradually introducing the molten raw material into the extrusion channel 8, as the molten raw material gradually accumulates on the two concentrated baffles 1201, when the pressure sensors 1214 behind each pressure plate 1213 on the two concentrated baffles 1201 are squeezed by a pressure greater than a certain fixed value, the hydraulic cylinder three 1211 is adjusted to drive the positioning plate 1212 to separate from the concentrated baffle 1201, and the concentrated baffle 1201 moves toward the rear mounting groove 11 under the push of the molten raw material, and the tightly stacked molten raw material is pushed to the extrusion plate 6 and completely covers the extrusion holes on the extrusion plate 6, thereby ensuring that the initially extruded plastic products are all shaped finished products, avoiding the high loss of molten raw materials caused by the extrusion of a large number of unshaped plastic products.

[0034] Specifically, in the process of the concentrated baffle 1201 deflecting toward the installation groove 11, the blocking belt 1204 seals the gap between the installation groove 11 and the concentrated baffle 1201 to prevent the molten raw material from entering the installation groove 11. At the same time, the forward and reverse motor 1209 is started, and the forward and reverse motor 1209 drives the pulling rope 1207 to reel in, so that the pulling rope 1207 has a pulling effect on the blocking belt 1204, so that the blocking belt 1204 is stored in the installation groove 11. At the same time, the pulling of the pulling rope 1207 accelerates the storage of the concentrated baffle 1201 to ensure that the concentrated baffle 1201 is fully fitted with the installation groove 11.

[0035] It should be noted that after the device is used once, the forward and reverse motor 1209 reverses to drive the pull rope 1207 to unwind, and the central baffle 1201 is gradually deflected toward the middle line position of the extrusion channel 8 under the action of the reset spring rod 1205. When the angle between the central baffle 1201 and the mounting groove 11 is below 75°, the hydraulic cylinder three 1211 is adjusted to drive the positioning plate 1212 to squeeze the central baffle 1201, so that the central baffle 1201 is quickly reset, thereby improving the convenience of operation.

The flow plate 304 fits with the inner wall of the feed barrel 301, and the inner wall of the feed barrel 301 near the bottom is fixedly connected with a mounting rod 310, and the top of the mounting rod 310 is fixedly connected with an intermediate connecting plate 302, and the outer wall of the intermediate connecting plate 302 is fixedly connected with a limiting guide plate 308, and there is a material feeding gap between the limiting guide plate 308 and the feed barrel 301.

[0038] Specifically, when adding molten raw materials, they are introduced between the limiting guide plate 308 and the feed barrel 301, and the rotating motor 307 is started. The rotating motor 307 drives the various rotating diverter plates 304 on the linkage frame 305 to rotate the molten raw materials, so that the molten raw materials can flow evenly from different positions of the feed barrel 301 to the bottom, avoiding the accumulation of molten raw materials and causing feed blockage. At the same time, when the molten raw materials slide down the inner wall of the feed barrel 301 from different positions, the electric heating tube 303 heats them evenly, avoiding the molten raw materials from cooling down during the transportation process, thereby improving the feeding effect.

[0039] It should be noted that, during the feeding process, the air compressor 313 is started, and the air compressor 313 introduces the high-temperature gas inside the feed barrel 301 into the hollow jet plate 312, and sprays it through the nozzle 311 to the molten raw material sliding on the inner wall of the feed barrel 301, thereby accelerating the falling of the molten raw material. When the last part of the molten raw material is added, the blowing of the compressed gas prevents part of the molten raw material from being retained on the inner wall of the feed barrel 301 and causing loss, and at the same time, prevents the retained part from cooling and solidifying and adhering to the inner wall of the feed barrel 301 and causing pollution.
