The full-automatic carbon rod extrusion molding machine comprises a machine frame and a main control device arranged on the machine frame and used for controlling the operation of all workpieces, wherein the machine frame is divided into an extrusion area and a cutting area, a material cylinder for containing raw materials, a feeding mechanism, a first-stage screw rod mechanism and a second-state screw mechanism are sequentially arranged in the extrusion area, a cutting mechanism, a carbon rod positioning mechanismand a carbon rod length fixing mechanism are arranged in the cutting area, a carbon rod channel is arranged between the carbon rod positioning mechanism and a carbon rod outlet of a second screw stirrer, and steam discharging devices are correspondingly arranged on a first screw stirrer and the second screw stirrer. According to the full-automatic carbon rod extrusion molding machine, automatic production can be realized, workers can control the start and stop of all the workpieces through the main control device so that a single worker can simultaneously control multiple equipment, the production efficiency is improved, and the production labor cost is reduced; and the two independent screw mechanisms are adopted to separate plasticizing and forming, the first-stage screw mechanism is responsible for plasticizing, and the second-stage screw mechanism is responsible for forming and extruding.

Description

technical field [0001] The invention relates to the technical field of carbon rod production equipment, in particular to a fully automatic carbon rod extrusion molding machine. Background technique [0002] Carbon rod filter, also known as sintered activated carbon filter, or CTO filter, carbon rod filter is a new type of depth filter. It is made of high-quality activated carbon as raw material, and its structure is composed of low-heat-melt adhesive, which is continuously extruded. The carbon rod filter element has the excellent adsorption performance of granular activated carbon, and effectively overcomes the carbon powder leakage defect existing in the use of all activated carbon filters. With the precise filtration characteristics of tubular elements, it can effectively remove organic matter, particles, rust, residual chlorine, and peculiar smell in the liquid. [0003] The reason why activated carbon can be a high-quality filter material is that it has a large surface...

AI Technical Summary

Problems solved by technology

[0006] The existing carbon rod production equipment has the following defects: 1. There is a contradiction when heating and cooling are put together. This contradiction exists in the existing single screw structure. The temperature of the front section is obviously higher than that of the back section, so that the middle hole A large amount of air and moisture in the micropores accumulate in the front section, which cannot flow smoothly to the back section and be discharged. After the carbon rods are solidified, they gather in the back section but cannot be produced smoothly, resulting in increasing internal pressure. In severe cases, The carbon rod at the exit will be squeezed out like a cannonball, causing very unbearable consequences

Therefore, in order to run smoothly in the existing linear single-screw carbon rod extruder, the quality of raw materials such as activated carbon must be improved to ensure that there is less moisture and air in the raw materials before normal production can be carried out. The cost is relatively high, leading to a very high increase in production costs; 2. In the production process of the existing technology, it is first heated, melted, mixed and then rapidly cooled and solidified. The temperature contrast is extremely large, and it is realized in a short period of time, which may easily lead to unstable product quality. 3. The extruders in the existing carbon rod production equipment are all separate individuals. Although the carbon rod is solid when it is just extruded, it is not stable and difficult to move at this time. It needs to be completely solidified and moved to the subsequent Cutting and molding operations are carried out in the equipment according to the required size, but because curing takes a certain amount of time, it takes up a lot of production time, and it is also prone to loss during the moving process, and the subsequent processing of fully cured carbon rods is more difficult, resulting in production Efficiency is reduced; 4. In the straight-line single-screw structure, the process of heating to high temperature and cooling to the holding temperature needs to be realized in the front and rear sections respectively, which is prone to temperature shifting, resulting in a decline in product quality
