Rubber rolling mill, which is rubber products processing in the p
24、rocess of one of the basic equipment. Since 1843 three-roll calendar application, we have 160 years of development history. From the modern to modern specifications and various new calendar will continue to emerge, its specifications, speed, semi product of high accuracy, a high degree of automation
25、 machinery, the machinery has become the modern calendar of the main structural features. At present production largest calendar has reached more than 1055 3000 (mm), roller line speed of up to 120(m / min) above, the semi-finished calendar has reached its thickness error within 0.0025 (mm). And ach
26、ieve full electronic control of the computer and automation level. The Closed Compound (mixer), rubber and plastic mixing refining is one of the main equipment. The development of modern mixer, a high-speed, high-pressure and high-performance characteristics, and is divided into low-speed (20 to the
27、 rotor speed / min), the velocity (speed of 30 to 40 / min) and high-speed (60 to speed / min) 3. In recent years also appear to speed in the 80 / mixer at high speed over armed Rubber extruder (screw extruder), the worlds first since 1879-screw extruder Since the birth of all kinds of screw extrude
28、r machinery in a large number of different varieties have been supporting complete specification has been adapted to different product performance characteristics of the request. If pressure extrusion machine, mainly for the shape of the semi-finished production; filter plastic extrusion machine for

To compound the pressure plate; desulfurization renewable plastic extruder for
30、 the desulfurization: extrusion dehydration mixing rubber extruder for dehydration and regeneration plastic dry: Cable extruder for the cable coated molding; row Gas extruder. The mixing compound got out of the air and water and volatile compounds, such as low-molecular-weight. These specifications
31、complete extrusion machinery, the development of the rubber industry and was credited. It has become the driving force of the rubber products processing and optimization of the equipment. Injection Molding Machine, also known as the Note Press, mainly for the production of rubber molded products. No
32、te pressure machinery, its structure, is divided into horizontal injection press, vertical injection press, injection machine and the Multi-Position Press Note 4. Press each note is divided into many different sizes of the specifications. Tire rubber industry is the largest number one product. Wheth
33、er raw materials from the use of rubber and rubber products, put out of rubber products which occupy the lions share of the market, consume about 80% of the volume of rubber resources. Therefore, the tire molding machinery is also important. Since the invention of pneumatic tire in 1888, with the de
34、velopment of the automobile industry, various specifications, the various properties of a large number of rubber tires. A high-performance, high-quality car, if there is no corresponding performance and quality of the tire support is equivalent to scrap general. And the development of tire industry
35、tire molding machinery participation is crucial. Tubeless tire or whether they would have to be certain to die molding machinery stereotypes. Forming particular tire, tire production is in the process of core processes, tire various parts of the assembly process, will soon cord, bead, wrapper, tread
36、, and other components of processed into paste composition tire embryo. Therefore tire molding machinery determines to a large extent the performance and quality of tires. As human socio-economic and cultural progress and development, a wide range of a large number of vehicles. Therefore the various
37、 types and specification is endless. Such as cars, buses, trucks, construction vehicles and other special vehicles and aircraft, which have their own dedicated tire varieties and specifications. In recent years there has high strength and high wear resistance of the steel skeleton radial tire, makin
38、g automobile tires, performance and the structure and quality to a new level. This constant tire molding machinery put out a higher demand. Tire molding machine many of the types, according to the method of forming: sleeve-law and two kinds of stickers; by shaping the contours of the drum: drum, sem
39、i-drum, and the core-wheeled four-wheel-core. In addition, all other uses of different shapes and rubber products, there is a basic molding process. Therefore a variety of rubber molding machines and even offers a dazzling. Only a wide variety of ring is tens of thousands of species on the number. T
40、his shows that the rubber molding machinery industry is also very complicated and very important. Vulcanization machinery, a variety of rubber products of the final steps in the processing machinery, mainly for the various rubber products, plastic, rubber products, such as sulfide processing. The ma
41、in structure of three kinds of forms: one is flat vulcanize, and the autoclave (including pressure autoclave) and the drum machine sulfide. Flat-curing the use of broader is more variety. In addition to direct use of vulcanized rubber products processing, can also be used in the plastics industry th
42、ermoplastic or thermosetting plastic plastics processing repression. Because of their body structure and working principle is basically the same. The types and forms are many. According to the purpose, has the vulcanized rubber model of flat products, with flat-curing machine, V-belt plate curing ma
43、chine, sheet plate curing machine. Vulcanized rubber products tank is the first production application of curing equipment, mainly for the vulcanization of rubber products work. Can also be used to autoclave the curing soles, adhesive tape and model products. Therefore, omnipotent said curing machin
44、e. Drum curing machine, belt and the V-belt two categories. Mainly used for curing surface shape and surface quality of the special requirements of thin strip of rubber products, such as tread rubber and plastic sheet printing and dyeing, such as the conduction band. If accompanied by the necessary
45、accessories device can be used to transport sulfide zone, belts and other similar products vulcanized rubber processing. Drum Machine continuous vulcanization sulfide, easy assembly and the formation of automated production lines. Substantially reduce labor intensity and improve efficiency and produ
46、ct quality.For the development of rubber industry, mechanical and process technology research determines its speed and level of development determines the performance and quality of products. Generally speaking, industrial technology research and product cycle faster some frequency. Changes in techn
47、ology and machinery cycle is slow, it decided to change the cycle of the life of the equipment, work efficiency and product quality. It is precisely because of machinery and equipment has a clear life, it makes the certain inertia of the operation. Thus create a difficult change or do not need rapid
48、 changes in the direct experience. This is a reality for many people, the community and even some scientific research and departments only attaches great importance to technology innovation and ignore changes in mechanical and technological advances and the development of one of the main reasons. Th
49、e mindset of the people is to determine awareness of changes and developments. Any material production originated in the first production practice on the real social needs of the objective.or the rubber industry development, which is not only the normal process of production is rubber products. Mechanical technology and the increasing need in-depth study of technology and joint development of modern commodity market competitive situation also not tolerate such people wait wait-and-see or delay time, and in addition
