Step 4, extrusion molding, in described screw-type extrusion machine 4, screw rod rotates, and sent into by raw materials for production in mould 5, raw materials for production are extruded into ring-shaped by the diameter progressive screw 52 in described mould 5, then are sent in shaping cover 6 shaping;
Step 5, cutting body, described hauling machine 8 draws trustship body, and cuts into kneed idler pipe by Pipe Cutting blanking machine 9.
Raw materials for production in this production craft step one adopt nylon and grafted material, the wherein mechanical property of nylon material, endurance is surrendered, hot strength, the mechanical performances such as case hardness are excellent, but nylon fusing point is at 215 DEG C, heat decomposition temperature > 300 DEG C, because nylon material is poor mobile performance near melting temperature, viscosity is large, so only adopt nylon to be that the body that raw materials for production make is not easy shaping, therefore in raw materials for production, have employed grafted material and compatilizer, improve its hot strength, additionally use polythene material simultaneously, nylon mobility in the molten state can be changed, be convenient to pipe forming.Find through experiment, in order to more excellent idler pipe performance, raw materials for production preferably include the nylon that described mass ratio is 76%-95%, and mass ratio is the grafted material of 3%-8%, and mass ratio is the polyethylene of 5%-20%.
In addition, in these raw materials for production, can also colouring agent be added with, and match colors with raw materials for production Homogeneous phase mixing, raw materials for production can be made to realize painted in extrusion moulding process and obtain coloured nylon carrying roller body; Because colouring agent is used for the nylon carrying roller body for different colours demand, plays the effect of toning, such as when needs nylon carrying roller body is black, in its raw materials for production, add a small amount of carbon ink.
When in above-mentioned steps two, raw materials for production are dry in drying machine 1, it should be noted that, need separately to carry out various material, wherein can adopt the dry 2-3 hour of nylon material, temperature upper limit is set as 120 DEG C, the dry 2-3 hour of polythene material, temperature upper limit sets 100 DEG C, waits all material not to be allowed for access in screw-type extrusion machine 4 when having moisture to discharge and temperature reaches the higher limit of drying machine 1 design temperature.
In above-mentioned steps three, barrel 41 carries out being heated to 200-300 DEG C by the heater of screw-type extrusion machine 4, and vavuum pump 3 can be utilized in screw-type extrusion machine 4 described in raw materials for production suction.At such a temperature, raw materials for production melting is respond well, and mobile performance is better for barrel 41; By vavuum pump 3, raw materials for production are called in screw-type extrusion machine 4, raw materials for production moisture when entering in screw-type extrusion machine 4 can be reduced and be mixed into, ensure nylon carrying roller body quality.
In above-mentioned steps four, shaping cover 6 needs to proofread with mould 5 and mates, shaping cover 6 and mould 5, the gasket seal of same model is specifically selected according to the diameter of produced idler pipe, shaping cover 6 is fixed in the barrel 41 in cooling device 7 pattern tool 5 direction, adjusts height and the depth of parallelism of shaping cover 6 mouth of pipe and mould 5 discharging opening; Must ensure that both are in a concentricity.According to the direct size of production body, regulate the height of idler pipe in cooling device 7, upper plane and the shaping cover 6 exit inside diameter lower plane of idler pipe keep level.
Hauling machine 8 in above-mentioned steps five is mainly used as to draw idler pipe IDE, namely trustship body from mould 5 discharging opening to shaping cover 6 until Pipe Cutting blanking machine 9 move horizontally power resources, regulated by the speed of hauling machine 8, can the molding thickness of adjusting carrier roller body fused raw material in shaping cover 6, the i.e. wall thickness of adjusting carrier roller pipe forming, until regulate the certain speed of hauling machine 8, the shaping wall thickness of idler pipe is made to meet actual requirement.
This a kind of nylon carrying roller tube manufacturing process, first be mixed into raw materials for production to nylon and grafted material to be configured and to mix, in drying machine 1, the drying of stewing material dewaters, start screw-type extrusion machine 4 heating its barrel 41 is heated, raw materials for production are put into barrel 41 melting, the raw materials for production of molten condition are sent into mould 5 by conveying screw rod 42 afterwards, rotated by the diameter progressive screw 52 of extruded mould 5 again and be extruded into ring-shaped material flow, material flow enters in shaping cover 6 again and is molded into trustship body, draw cutting finally by hauling machine 8 and Pipe Cutting blanking machine 9 and form the tube coupling shape nylon carrying roller body needed, this nylon carrying roller tube manufacturing process is by adopting nylon material and grafted material as raw material, the extrusion molding carrying out idler pipe is shaped, idler pipe is produced with the method for extrusion molding or injection moulding relative to existing employing polyethylene, adopt the raw materials for production of nylon and grafted material mixing, nylon endurance is surrendered, hot strength, case hardness excellent performance, grafted material can reduce viscosity during nylon melt-flow, be convenient to pipe forming, therefore this manufacturing process effectively can improve wearability and the intensity of idler pipe, improve the life-span of idler pipe, in addition, also the idler pipe that tradition utilizes nylon injection-molding mode forming method to manufacture is compared, the speed of production of this technique is fast, production efficiency is high, the nylon carrying roller body size manufactured is accurate.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
