Wuhan Handern layered equipment
1. Impregnation and drying equipmentImpregnation, drying and winding are a continuous production device. Its structure is simple, and the requirements for material and processing guess are not high, so it is easier to manufacture. The main parts are briefly described as follows: www.handern.com hollow board equipment
(1) Dipping and gluing machine There are two types of horizontal and vertical. However, the main equipment is the weaving rack, the dipping tank, the glue volume adjustment device, the loading roller, heating and tensioning, etc. www.handern.com There are two types of hollow board equipment, V-type and U-type. The U-type is mostly used for mother-type leaching into experiments, small batch production or single-sided immersion flow, and its immersion distance is short. U-shaped pushers are mostly used for vertical immersion. It is impregnated with thermal insulation jacket, which can pass 25-30 ℃ warm water to control the viscosity of the fat. If the temperature is too high, the solvent will volatilize and the polymerization reaction surface will be accelerated. www.handern.com Hollow board equipment
There are two kinds of glue volume adjustment devices: squeeze roller type and auxiliary knife type. The squeeze roller type is suitable for base materials with high density, tight fiber set period, and poor water absorption. The amount of dipping (glue amount) is easy to control, so it is widely used. The scraper type is simple, but it is only suitable for impregnating materials with good water absorption. The amount of impregnation is not easy to control, and it is easy to hurt the base material, so it is limited. www.handern.com Hollow board equipment
(2) The purpose of the drying room is to remove the immersed solvent, moisture and volatiles, while further condensing the resin. The outside of the dry house is made of geothermal materials, equipped with exhaust and ventilation devices. With the dip machine, it is also available in horizontal and vertical types. The female drying room is long and the ancient area is large. As long as the vertical type is high, some need 12 to 13m. It is often used for base materials with high tensile strength, such as cloth and glass cloth.
Temperature distribution of drying oven: vertical is divided into upper, middle and lower sections, the lower section is 30～60℃, the middle section is 60～80℃, and the upper section is 85-130℃. Each type is also divided into three sections, the inlet is about 10℃, the middle is 130～150℃, and the outlet is below 100℃. When the temperature is high, small bubbles will occur on the immersion surface. If the temperature is too low, the output will be affected. www.handern.com Hollow board equipment
The heating of the drying room generally uses high-pressure steam, hot air transfer, the temperature is easy to control, and it is also safe. Electric heating is not economical, only used for high temperature resin.
2. Multi-Laminator
The lamination equipment is mainly multi-laminator and Yintong hydraulic press. This section only introduces the laminator. www.handern.com Hollow board equipment
Multi-layer laminators are used to produce laminates with large tonnages, usually 2,000 to 5,000 electricity. The operating principle is the same as that of a push-down hydraulic press. The difference in the knot is that a dozen or more to dozens of working complete boards are added to the two press plates, so that a dozen to dozens of layers can be laminated at a time. Plywood. The maximum distance between each layer of work pads is 100-30mm, but its range of activity is large, and it can talk up and down with two pillars. There is a water channel in each layer of backing plate, which can pass high-pressure steam or cooling water. Small laminators are also electrically heated. www.handern.com Hollow board equipment
3. Winder
Laminated tubes, rods, etc. are all used in the state burning machine, which is composed of several rollers. It is only necessary to remove the tube roller when manufacturing the laminated bar. www.handern.com The large pressing and hollowing equipment and the front and back support rollers are the core of the machine. The front support rollers have heating devices and the roller temperature should be strictly controlled.
