Abstract
Description
Technical Field
[0001] This utility model belongs to the field of composite material pultrusion profile technology, and specifically relates to an impregnation tank for wet molding process. Background Technology
[0002] With the rapid development of the composite materials industry, more and more products are using composite materials, and the development and optimization of composite material molding processes are becoming increasingly important, while the requirements and standards for products are also becoming higher and higher.
[0003] Especially for the new energy vehicle industry, the requirements for stability and efficiency in the production of small cross-section products are becoming increasingly stringent. At present, the impregnation tank structure of pultrusion production equipment is relatively simple. The problems are not obvious when producing large cross-section and thick products. However, when producing small cross-section and thin products, the product qualification rate will be affected by issues such as resin viscosity and fiber felt control. Utility Model Content
[0004] This invention provides a dipping tank for wet molding processes, which can solve the problems pointed out in the background art.
[0005] A wet molding process dip tank includes a dip tank body, an agitator inside the dip tank body driven by a drive component, a heater on the dip tank body, a yarn pressing frame assembly inside the dip tank body for confining yarn within the dip tank body, and a tension unwinding drum at the end of the dip tank body.
[0006] Preferably, the yarn pressing frame assembly includes a mounting component and a yarn pressing component. The yarn pressing frame assembly is mounted on the impregnation tank body via the mounting component, and the yarn pressing component is connected to the mounting component and extends in the depth direction of the impregnation tank body.
[0007] Preferably, the yarn pressing component is a U-shaped yarn pressing tube, and the mounting component is a horizontal mounting tube, which is detachably connected to the impregnation tank.
[0008] Preferably, the horizontal mounting tube is a horizontal square tube, the impregnation tank is provided with a mounting sleeve, and the mounting sleeve is provided with a positioning pin. The horizontal square tube is locked to the mounting sleeve by the positioning pin, and the U-shaped pressing tube has a circular cross-section.
[0009] Preferably, the driving component is a geared motor, which is fixed to the lower outer side of the impregnation tank, and its output end is connected to the stirrer for transmission.
[0010] Preferably, the heater is located at the bottom of the impregnation tank.
[0011] Preferably, both sides of the impregnation tank in the width direction are provided with a yarn pressing frame assembly and a tension unwinding drum.
[0012] Beneficial effects: This utility model provides a resin impregnation tank for wet molding process, which can effectively improve the product qualification rate affected by resin viscosity, fiber felt deviation and other factors, improve the first pass rate of products, reduce material consumption costs, thereby saving costs and improving production efficiency;
[0013] Setting up a heater ensures that the resin is at the appropriate temperature. If the resin temperature is too low, too much resin will stick to the yarn bundle. Since resin is fluid, if too much goes into the mold, it can easily cause the yarn bundle to shift, and the fiber felt will also deviate. Therefore, setting up a heater can effectively improve the above problems.
[0014] Unwinding the fiber felt roll using a tension unwinding drum applies a force to the fiber felt, preventing it from sagging excessively, which can cause the fiber felt to deviate from its intended path.
[0015] In addition, the yarn pressing frame assembly has been improved. Previously, the structure was generally a horizontal limiting tube welded on. This structure is easy to install and disassemble and convenient to use. In addition, yarn pressing frame assemblies and tension unwinding drums are provided on both sides, so that both sides can be used at the same time or one side at a time without affecting each other.
