Abstract
The utility model provides an improved high-efficient dual-screw rod machine, which is composed of a machine base, a machine body, a motor, a barrel, two screw rods and a kneading block, wherein, the kneading block is composed of a plurality of sets of combinations and is arranged in the barrel, wherein, the length of the barrel is corresponding to the length of the kneading block. The novel dual-screw rod machine has the production capacities of high-efficient shear dispersing and mixing; compared with the traditional dual-screw rod machine, the production capacity is improved by a plurality of times, and the novel dual-screw rod machine has the advantages of high quality, high stability and so on. The novel dual-screw rod machine is applied in the modified processing technology of plastic raw materials.
Description
Technical field:
The utility model relates to field of machining, particularly a kind of efficient dual-screw-stem machine of modified that is used for the plastic material modify and graft.
Background technology:
It is to add some chemical raw materials in plastic material that the tradition plastic cement is sheared modify and graft, utilize the high shear of the kneading piece of parallel dual-screw extruding machine, high engagement, plastic material is constantly sheared in the body of parallel dual-screw extruding machine to be disperseed, while is mixed milling again, finishes the modify and graft of plastic material.Because chemical raw material and plastic material modify and graft need the specific reaction time, therefore the parallel dual-screw extruding machine of tradition can only reduce the twin-screw rotating speed, allow chemical raw material and plastic material low-speed running in twin-screw, just can reach the specific reaction time of chemical raw material and plastic material.
Because the parallel dual-screw extruding machine structure of above tradition and chemical raw material and plastic material modify and graft need the specific reaction time, as can be seen, the defective that the parallel dual-screw extruding machine of tradition exists efficient and quality not to improve simultaneously, thus have a strong impact on its production efficiency.
Summary of the invention:
The purpose of this utility model provides a kind of efficient dual-screw-stem machine of modified that is used for the plastic material modify and graft, is applied in the plastic material modification processing technology, improve the production capacity several times than traditional dual-screw-stem machine, and quality is more stable.
The purpose of this utility model is to be achieved by the following scheme, the efficient dual-screw-stem machine of modified, constitute by support, fuselage, motor, barrel, twin-screw, kneading piece, described kneading piece is constituted by many covers, be arranged in the barrel, the length of wherein said barrel is corresponding with the length of mediating piece, when guaranteeing the high rotating speed of screw rod of double screw extruder, and the specific reaction time abundance of chemical raw material and plastic material modify and graft needs.
The efficient dual-screw-stem machine of above-mentioned modified, described kneading piece is by constituting more than 30 covers.
The utility model is applied to have the production capacity of efficient shearing dispersion, mixed milling in the plastic material modification processing technology.Improve the production capacity several times than traditional dual-screw-stem machine, have advantages such as high-quality, high stability simultaneously.
Description of drawings:
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic diagram;
The specific embodiment:
Shown in Fig. 1 to 2: the efficient dual-screw-stem machine of modified is made of support 1, fuselage 2, motor 3, barrel 4, twin-screw 5, kneading piece 6.The kneading piece 6 of described screw rod is by constituting more than 30 covers, be placed in the inside of material letter 4, wherein the length of barrel is corresponding with the length of mediating piece, can guarantee that like this twin-screw 5 is when high rotating speed, the specific reaction time abundance that chemical raw material and plastic material modify and graft need, thereby improve the production capacity of shearing dispersion, mixed milling, improve the stability of product simultaneously.The utility model is applied in the plastic material modification processing technology.
