Description
Technical Field
The invention relates to the field of glass fiber pipeline manufacturing, in particular to a rotary sizing device.
Background
Many underground pipelines or ground pipelines, including large tap water pipelines, sewage pipelines, oil pipelines, gas pipelines and the like, are mostly made of plastic materials, and have lower strength.
At present, a plurality of manufacturers adopt glass fiber mixed raw materials to manufacture pipelines, and the adopted matched raw materials are different from each other, so that different supporting strengths and weights, for example, are generated; the existing glass fiber plastic pipeline is weak in strength and toughness under the general condition, the probability of pipeline breakage is increased, the stability of the pipeline in use is reduced, and the device used by the manufacturing method is long in time for curing the pipeline and is not suitable for the requirement of rapid production.
In the preparation process of the glass fiber pipe, glue is required to be smeared on the glass fiber pipe material to be wound on the core mold, the glass fiber pipe material and other glass fiber pipe materials wound on the core mold are bonded together, and then the glass fiber pipe is manufactured after the subsequent process steps. In the prior art, glue is generally coated by immersing a glass fiber pipeline material into a glue box, or winding the glass fiber pipeline material onto a core mold, and then coating the glass fiber pipeline material between the fixed glue box and the core mold with glue by a fixed glue box fixed on the outer wall of the core mold; the sizing process only coats a brain of the glue on the glass fiber pipeline material, so that uneven coating is easily caused, and excessive glue coated on the glass fiber pipeline material cannot be removed smoothly, so that the quality of the subsequent glass fiber pipeline is affected.
Disclosure of Invention
The invention aims to: aiming at the problems in the prior art, the invention provides the rotary sizing device which can uniformly coat the glue on the glass fiber pipeline material, smoothly discharge a plurality of glues and effectively ensure the gluing quality of the glass fiber pipeline.
The technical scheme is as follows: the invention provides a rotary sizing device, wherein a rotary cylinder is arranged on the outer wall of a core mould and is rotationally connected with the inner wall of a fixed cylinder through a bearing, the fixed cylinder is fixed on a frame through a bracket, and a driving mechanism is used for driving the rotary cylinder to rotate around the core mould; the top and the bottom of the front end of the fixed cylinder are respectively provided with a glue injection hole and a glue discharge hole; the front end inner wall of the fixed cylinder is connected with the front end inner wall of the rotary cylinder, and the tail end inner wall of the fixed cylinder is overlapped with the tail end outer wall of the rotary cylinder.
Preferably, in the driving mechanism, a driving sprocket is fixed on an output shaft of the gear motor, a driven sprocket is fixed at the front end of the rotary drum, and the driving sprocket is connected with the driven sprocket through a chain. The gear motor drives the driving sprocket to rotate, and the driving sprocket drives the driven sprocket to rotate through the chain, so that the rotary drum is driven to rotate around the core mold.
Further, the inner wall of the tail end of the rotary cylinder is further provided with a thread groove with a preset length, and the initial end of the thread groove is positioned at the rear side of the glue inlet. After the glue falls onto the core mold from the glue injection hole, the glue can be quickly and uniformly coated on the fiber cloth on the surface of the core mold under the rotation action of the rotating cylinder and the pushing and extrusion action of the thread groove, and the redundant glue can be effectively discharged from the inner part of the rotating cylinder and recovered after being discharged through the glue discharge hole.
Preferably, the thread depth of the thread grooves decreases sequentially from the start to the end. The depth of the thread grooves is sequentially reduced so that the excessive glue can be effectively discharged out of the rotary drum when the rotary drum rotates.
Further, a clearance space is formed between the inner wall of the front end of the fixed cylinder and the inner wall of the front end of the rotary cylinder and the core mold. The arrangement of the clearance space enables a certain clearance to be formed between the inner walls of the front ends of the fixed cylinder and the rotary cylinder and the core mould, so that glue entering from the glue injection hole on the fixed cylinder can fall onto the core mould directly and is smeared on pipeline materials on the core mould.
The beneficial effects are that: when the rotary sizing device works, glue is injected through the glue injection hole at the top of the fixed cylinder, the glue falls onto the glass fiber pipeline material on the core mold, when the glass fiber pipeline material on the core mold is pulled into the rotary cylinder, the driving mechanism drives the rotary cylinder to rotate along the core mold, in the rotating process, a rotary friction force is generated between the inner wall of the rotary cylinder and the glass fiber pipeline material on the core mold, the glue is uniformly smeared onto the glass fiber pipeline material under the rotating action of the rotary cylinder, in the rotating process, the glue can bond the outer glass fiber pipeline material and the inner glass fiber pipeline material together more rapidly, and the redundant glue can be discharged out of the rotary cylinder under the rotating action of the rotary cylinder. Therefore, the device can uniformly smear the glue on the glass fiber pipeline material, smoothly discharge a plurality of glue, effectively ensure the glue spreading quality of the glass fiber pipeline, realize an automatic production process, have higher production efficiency and are suitable for rapid production.
