Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of unsaturated resin processing, in particular to a filling device for unsaturated resin production. Background Art
[0002] Unsaturated polyester resin is the most commonly used type of thermosetting resin. It is generally a linear polymer compound with ester bonds and unsaturated double bonds formed by the condensation of unsaturated dibasic acid and diol or saturated dibasic acid and unsaturated diol. Usually, the polyesterification polycondensation reaction is carried out at 190-220°C until the expected acid value (or viscosity) is reached. After the polyesterification polycondensation reaction is completed, a certain amount of vinyl monomer is added while hot to form a viscous liquid. Such a polymer solution is called unsaturated polyester resin.
[0003] When unsaturated polyester resin is made into a tube, it is often necessary to heat it to a certain extent in order to ensure its own fluidity so that its temperature is always kept in a stable range. Otherwise, once the unsaturated polyester resin solidifies, it will block the filling equipment and affect the filling efficiency. However, the current filling equipment often only has an electric heating wire on its outer layer for heating. The temperature cannot affect the unsaturated polyester resin deep in the equipment, and blockage problems may still occur. Utility Model Content

[0006] The upper surface of the bottom plate is fixedly connected with a mounting frame, and the filling mechanism is arranged inside the mounting frame;
[0007] The filling mechanism includes a filling tank fixedly connected to the inside of the mounting frame, a hollow cavity with a ring-shaped cross section is opened inside the side wall of the filling tank along its length direction, a heating wire is fixedly connected inside the hollow cavity along its length direction, a vertical tube is vertically fixedly connected to the top of the filling tank, a plurality of discharge ports and feed ports are respectively horizontally penetrated at the top and bottom ends of the outer surface of the vertical tube, a fan-shaped guide plate is fixedly connected to the outer surface of the vertical tube and located below the plurality of discharge ports, a rotating shaft is vertically rotatably connected to the top of the filling tank, and a feeding blade matched with the inner diameter of the vertical tube is fixedly connected to the outer surface of the rotating shaft along its length direction.
[0008] Furthermore, the central axes of the vertical tube and the rotating shaft are located on the same straight line.
[0009] Furthermore, the bottom end of the filling tank is connected to a filling head, and the top end of the filling tank is connected to a feeding pipe.
[0010] Furthermore, the top end of the feed pipe is connected to a feed hose.
[0011] Furthermore, a motor is fixedly connected to the top of the filling tank, and an output shaft of the motor rotatably passes through the upper surface of the filling tank and is fixedly connected to the top of the rotating shaft.
[0012] Furthermore, a conveyor belt is provided on the upper surface of the bottom plate and below the filling mechanism along the length direction of the bottom plate.
[0013] Compared with the prior art, the beneficial effect of the utility model is as follows: the filling device for unsaturated resin production is provided with a filling mechanism. When the device is in use, the rotating shaft in the filling mechanism will continue to rotate, and the feeding blades on its surface will also rotate synchronously and continuously. During the rotation process, the unsaturated polyester resin at the bottom end of the filling tank will enter the interior of the vertical tube through the feed port and then be transported upward, and finally be discharged from the discharge port. After being discharged, it will flow to the side wall surface inside the filling tank under the action of the umbrella-shaped guide plate and continue to flow downward. In this process, the resin can be heated by the electric heating wire inside the side wall of the filling tank, and the structure inside the filling tank can drive the resin to flow continuously, so there will be no problem of resin solidification and blockage.
