Description

An extrusion device for producing and processing plastic optical fibers with uniform discharge Technical Field

[0001] The invention relates to the technical field of plastic optical fiber production equipment, in particular to an extrusion device for producing and processing plastic optical fibers with uniform material output. Background Art

[0002] Fiber optic cables generally consist of two or more optical fiber cores, which are located in a protective coating and covered with plastics such as PVC in an outer casing. Usually, tight-buffered optical fibers are produced using extrusion molds. With the continued growth of the global optical communications market, companies with lower manufacturing costs are more competitive. Currently, the industry's tight-buffered optical fibers are produced on plastic sheathing extrusion production lines.

[0003] The material storage barrels of general sleeve plastic extruders are mostly conical barrels. The storage capacity of such storage barrels is small and the material storage space of the sleeve plastic extruder is wasted. However, when a square storage tank is used, the bottom is flat and the material is left at the bottom of the storage tank when it reaches the bottom of the storage tank. It is difficult to completely squeeze the extruded material at the bottom of the storage tank into the extruder, which not only wastes the material for plastic optical fiber production, but also makes the material adsorbed at the bottom of the storage tank difficult to clean, which can cause the material to solidify and cause the extruder to be blocked. Summary of the Invention

There are several filling pipes, and several filling pipes are arranged corresponding to the filling ports.

[0015] Furthermore, the transmission mechanism includes a motor, which is fixedly connected to the inner wall of the motor. The output end of the motor is connected to a transmission shaft. The end of the transmission shaft away from the motor is rotatably connected to the inner wall of the extrusion block. A belt is sleeved on the outer surface of the transmission shaft. The belt is rotatably connected to the connecting frame at a point away from the transmission shaft. The connecting frame is fixedly connected to a connecting rod on the side away from the supporting rotating rod, and the connecting rod is arranged at the edge of the connecting frame.

[0016] Furthermore, the outer surface of the connecting rod is movably connected to a connecting mechanism, which includes a tripod, which is rotatably connected to the outer surface of the connecting rod.

[0020] The present invention has the following beneficial effects:

[0021] (1) The material can be injected into the material trough for pre-storage, and the hydraulic cylinder controls the extrusion mechanism to extrude the material inside the material trough, so that the material stored in the material trough enters the former through the pressure generated by the extrusion, and the material entering the former is formed by the pressure of the extrusion, and is extruded through the outlet, and is stored by the storage mechanism to wait for the next production process. The outlet mechanism is conveniently disassembled by the threaded connection of the limit frame, and the outlet mechanism is convenient for inspection and replacement. The device can be supported and placed by the placement seat, and the storage device can be conveniently connected to the bottom of the main body by opening a slot on the placement seat, thereby increasing the practicality of the device.

[0022] (2) The conical barrel-shaped storage tank is replaced by the material tank. Compared with the conical storage tank, the storage volume of the material tank is increased in the same installation area of ​​the storage tank, thereby avoiding wasting the material storage space of the plastic extruder. The material injector can be connected to the top of the filling pipe to fill the fluid material into the material tank through the filling port, and the extrusion block is driven by the connection between the hydraulic cylinder and the limit plate to extrude the material inside the material tank, thereby completing the production and processing technology of the plastic optical fiber by extruding the material inside the material tank.

[0023] (3) The hydraulic cylinder controls the extrusion mechanism to extrude. When the material inside the material trough reaches the bottom and the bottom of the extrusion block is squeezed to the bottom of the material trough, the transmission shaft is driven to rotate by the motor, and the connecting frame is driven to rotate by the belt. The barrel support rotating rod is connected to the inner portion of the extrusion block to increase the stability of the connecting frame, thereby driving the connecting rod to rotate. The rotating connection between the connecting rod and the tripod can be connected to the tripod and the connecting plate through the double-head connector, which can drive the push frame to move up and down on the inner wall of the movable trough. When the bottom of the push frame leaves the bottom of the material trough, the elastic steel sheet will rebound due to the lack of extrusion force, thereby scraping off the material stuck to the bottom of the material trough through the push claws at both ends, and the elastic steel sheet can be pushed to the bottom of the material trough through the connecting groove. After the downward extrusion, the opening and closing plates can be pushed open by the material to avoid pushing the material back to its original position. The material at the bottom of the material slot can be gradually moved to the interior of the former at the center of the bottom of the material slot through multiple elastic steel sheets, and the opening and closing plates can be prevented from opening and closing backwards through the limit sheets, so that the opening and closing plates can be opened and closed in only one direction, which is convenient for pushing and scraping the material at the bottom of the material slot, and avoids the material being left at the bottom of the storage slot when it reaches the bottom of the storage slot due to the flat bottom, thereby facilitating the complete extrusion of the extrusion material at the bottom of the storage slot into the interior of the extruder, reducing the waste of materials for the production of plastic optical fibers, and facilitating the cleaning of the material adsorbed on the bottom of the storage slot, reducing the phenomenon of material solidification causing blockage of the extruder.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
