Description
Technical Field
The utility model belongs to the technical field of drinking water tank production, concretely relates to blowing drinking water tank overlap grinding device.
Background
Extrusion blow molding is a method of making hollow thermoplastic articles. Widely known blow-molded objects are bottles, drums, cans, cases and all containers for packaging food, beverages, cosmetics, pharmaceuticals and daily necessities. Large blow-molded containers are commonly used for packaging of chemical products, lubricants, and bulk materials. Other blow molded articles are balls, bellows, and toys. For the automotive industry, fuel tanks, car bumpers, seat backs, center brackets, and arm rests and head restraint covers are all blow molded. For the machinery and furniture manufacturing industries, blow molded parts have housings, door frames, shelves, crockery or boxes with one open face.
The most common blow molding extrusion material is high density polyethylene, and most drinking water cans are made using this polymer. Other polyolefins are also often processed by blow molding. Styrene polymers, polyvinyl chloride, polyesters, polyurethanes, polycarbonates, and other thermoplastics may also be used for blow molding, depending on the application.
The extrusion blow molding process consists of 5 steps: 1. plastic parison (extrusion of hollow plastic tube); 2. closing the split mold on the parison, clamping the mold and cutting off the parison; 3. blowing and expanding the mold cavity, adjusting the opening and keeping a certain pressure during cooling; 4. opening the mold and discharging the blown part; 5. trimming the flash to obtain a finished product.
The cooling time is an important process parameter for controlling the appearance quality, performance and production efficiency of the article throughout the blow molding process. The proper cooling time is controlled to prevent the parison from deforming due to elastic recovery, so that the product has regular appearance, clear surface image and text and excellent quality. However, if the cooling time is too long, the crystallinity of the product increases, which results in a decrease in toughness and transparency, an increase in production cycle time, and a decrease in production efficiency. If the cooling time is too short, the blown container may be stressed and become porous, affecting the quality of the article. In the prior art, a cooling mode of injecting cooling water is generally adopted in the cooling process of blow molding of the drinking water tank, the cooling time is not easy to control, and meanwhile, the cooling is not uniform, so that the toughness and the transparency of the drinking water tank do not reach the standard.
