Problems solved by technology

The service life of this knife rod is short, and the reasons are as follows: Although the 45﹟ steel pipe has been quenched and tempered, it still cannot withstand the friction and extrusion force generated by the continuous cutting and extrusion of the large grooves and small grooves on the surface of the knife roller for a long time , it is difficult to avoid the tooth wear, cracking and scrapping; the dough contains salt and alkali, which corrode the knife roller, and it will be scrapped due to rust soon after use; the surface of the knife roller made of 45﹟ steel pipe is densely covered with large grooves and For small grooves, because the friction coefficient of 45﹟ steel pipe is > 1, it should be lubricated with edible oil frequently during use, otherwise the knife will stick; in addition, the previous knife rod (also known as: knife roller, knife stick) is easy to breed bacteria, Mildew occurs because the blade does not have the function of inhibiting the growth of mold
If the outer surface is galvanized or nickel-plated, the metal particles that fall off are harmful to the human body, because the coating does not have affinity with the human body

Embodiment 1

[0033] Embodiment 1, taking a 550×1.5mm round knife thickened noodle knife (referred to as "workpiece") as an example:

[0034] Step 1: Cleaning and drying: Clean and remove the large grooves and small grooves densely covered with rust-proof oil and stains on the surface of the knife rod in a constant temperature drying room, and use metal detergent and degreaser for cleaning in a weight ratio of 1:1 The liquid cleaning and drying linkage device puts the cleaned workpiece into the drying oven, the temperature is controlled at 60°C, and the dried workpiece is loaded into the special fixture to enter the next step. The cleaning and drying linkage device adopts a high-pressure spray cleaning machine;

[0035] The second step: workpiece pretreatment sandblasting: spray the outer circle with diamond W10 micropowder, and use physical methods to etch the surface of the workpiece, so that the coated diamond-like film forms the frame foundation;

[0036] The third step: pretreatment a...

Embodiment 2

[0048] Example 2: Take the 330×1.5mm thickened noodle knife as an example:

[0049] The first step: cleaning and drying: clean and remove the large grooves and small grooves densely covered on the surface of the knife rod in a constant temperature drying room. The liquid cleaning and drying linkage device puts the cleaned workpiece into the drying oven, and the temperature is controlled at 60-70°C. The dried workpiece is loaded into the special fixture to enter the next step.

[0050] The cleaning and drying linkage device is: the high-pressure spray cleaning machine is sent to the workpiece to be cleaned by the conveyor belt or the suspension line, and after a certain procedure, the workpiece is degreased, cleaned, dried, and then automatically sent out by the conveyor belt;

[0051] The second step: workpiece pretreatment sandblasting: spray the outer circle with diamond W10 micropowder, and use physical methods to etch the surface of the workpiece, so that the coated diamon...

Abstract

The invention discloses a process of a chromium oxynitride and diamond-like carbon film (DLC) composite coating fine dried noodle knife roller or stick. The process comprises the following steps of cleaning, drying, performing pre-treatment, coating a NO2Cr film layer as a transition layer (an anchoring layer) and coating a DLC outer film layer. By utilizing the process disclosed by the invention to coat a diamond-like carbon film on the fine dried noodle knife roller or stick, the hardness, toughness, wear resistance, corrosion resistance, antibacterial performance and lubrication performance of a fine dried noodle knife bar can be improved, so that the service life can be prolonged by 8-10 times. The process disclosed by the invention can be widely applied to other food machines.

Description

technical field [0001] The invention relates to food processing machinery, in particular to a high-tech NO 2 Cr-DLC composite coating technology deposited NO on the surface of the noodle cutter bar (also known as: knife roll, knife bar) made of 45﹟ steel 2 Cr-DLC (chromium oxynitride + diamond-like carbon film) composite coating process. Background technique [0002] China is the largest producer of flour products in the world, and vermicelli is an indispensable main food in the daily life of ordinary people. At present, the varieties and production methods of dried noodles are tending towards mechanization, specialization and standardization. Food machinery such as single-knife noodle cutters, multi-knife noodle cutters, and dried noodle production lines have achieved specialized production. [0003] All noodle processing machines are inseparable from the knife bar (also known as: knife roller, knife stick), and the knife bar is the main tool for cutting the dough rolled...
