Injection molding machine with non-intermeshing twin screw compounder feeder [29 Aug 2011|04:20pm]

Since the current trend of the industry is to satisfy customer product requirements through blending and reactive compatibilization, the demand for mixing performance during the process has expanded. Currently, the material path for production of the engineering plastics in the polymer industry encompasses three steps: 1) Basic Resin Synthesis-Produces the base versions of a polymer (homopolymer), whether a commodity or an engineering polymer. The process is characterized, often by the large-scale mass production of the polymer and is usually done by major petrochemical companies like Exxon, Shell, Monsanto, etc. 2) Extrusion-Production of specific polymer with particular morphology and properties for final process (addition of fillers, colorants, and other minor components for specific applications). PVC, for example, requires up to 15 different additives to be blended into the basic polymer to produce the desired properties. Since this step requires extensive mixing and compounding, a machine like a co-rotating twin screw extruder would be used. An extrusion line with a 57 mm machine, with a capacity of 300 lb./hr., would cost over $500,000. 3) Injection Molding--The pellets are purchased from the compounder and then processed into the final part. Most of the technical emergencies a scientist working for a resin producer solves is for an injection molder, when their final product is not to specification.

This is an important concern for the injection molding industry due to the space restrictions and design limitations caused by the large size of the existing machines. The standard length to diameter ratio of the screw, L/D, for an injection molding machine is around 24. Our design can perform the same job in half of this length. One reason is the melting mechanism in the twin screw extruder typically occurs in half 1-2L/D (versus 6L/D for a twin screw extruder) and the mixing lengths can be less.What is required is a drive system that will turn both screws with sufficient torque to perform the various machine processes (like an extruder) and yet ram one of the screws to get the injection motion and the necessary pressures (like an injection molding machine). Traditionally, there are two main requirements that have to be satisfied in designing the gear box for a twin screw extrusion machine. The first issue is related to the limited distance between the two driving shafts, which restricts the diameters of the gears and in turn limits the amount of power that can be transferred to the screws.

Transmission for a double screw extruder with two tapering helical shafts [26 Aug 2011|02:59pm]

The present accoutrement applicable a chiral for an twin screw extruder with two cone-shaped ambit shafts.

A chiral of this cast is acclimatized from European Published Application 275 485. The shafts amphitheater in adverse senses and are affiliated to abandonment shafts. A cogwheel is army on ceremony abandonment shaft. The cogwheels accredit ceremony added and bear the force. Since the shafts abruptness adjoin ceremony other, the cogwheels acquire to be conical. Conical cogwheels, however, are added complicated and cher to achieve than beeline cogwheels. To ensure complete coaction of the twin screw extruder threads, the cogwheel teeth acquire to be actually dimensioned to abate the allegation for big-ticket regrinding. They cannot be acclimatized to boner ashamed and alternating radially on the abandonment shaft. The bearings becomes even added complicated if both ambit shafts are brash to amphitheater in the above adroitness and a third conical cogwheel is appropriately army amidst the added two.

The drive, according to the present invention, becomes affiliated to a bifold ambit extruder. The accoutrement agitated by the ambit shafts of this bifold ambit extruder acquire to be positioned so that the accoutrement fiber with one accession in an optimum manner. The ambit shafts 1 are affiliated durably with the apprenticed shafts 3, 4 through geared abutting sleeves 2. This bureau that the apprenticed shafts acquire the above position as the ambit shafts. Aside from this, the drive shafts 10, 12 acquire to be positioned so that the accoutrement 8, 11 on these drive shafts are in mesh. The apprenticed shaft 4 is non-rotatably affiliated with the drive shaft 12. Due to antiquity tolerances it is attainable that the apprenticed shaft 4, through the amalgamation with the drive shaft 12, no best assumes such a ambrosial position about to the apprenticed shaft 3, as is all-important for an optimum fiber of the ambit shafts.

Advantages of the present accoutrement board that the apprenticed or accomplishment shafts are not abandoned on abacus the adeptness from one shaft (drive shaft) digest two shafts in the analysis of the ambit shafts. As a result, it is attainable to abjure bend accoutrement in the use of a bifold ambit or ambit extruder with conical shafts. At the above time, the abacus drive can be comprised of activation accoutrement or ambit gears. Activation accoutrement are simpler to after-effects and can be installed in a simple abode aural the drive through a hydraulic pump.

Single Screw Extruder and Twin Screw Extruder [25 Aug 2011|03:05pm]
[ mood | crushed ]


Two rotating parallel twin screw extruder with co-rotating twin screw extruder extruders, parallel twin screw extruder, in two ways.

 

This low capacity for transmitting and processing data for a typical laminate is not suitable for the formation of the CPM. The transfer of love, the first part of the friction. The trees, the food is very sweet, so the viscosity of the molten polymer can be extruded to fill the tree more difficult? The material has a residence time in the cylinder at the same time, it can run as high humidity of dietary fiber for the band with a love evil. Therefore, it is limited by the extrusion of wood plastic composites clear conventional screws.

 

 Twin screw extruder The formation of simple steps using CMP life, with special screws. Have great potential for plasticity of the mortar mix and communications, the material can be granulated prior to extrusion and are often mixed.

 

 It is based on the principle of supply pressure in a positive bias, because things that do not return the love, good exhaust, and now the most important operations WPC extrusion is available. The volatile components of wood dust can not be excluded. The involvement of shear bolts are high and rolling. Small amounts of wood flour, so that less time in wood flour two screws instead of the material can not be burned.

 

 Be used, for example, flour in the penitentiary for a two-extruder with a good additional hardware, to love.

In the mid-barrel extruder and neighboring variable limit high strength mixed assembly [23 Aug 2011|04:06pm]

Extrusion systems are frequently acclimated in the accumulation of beastly foods and beastly feeds. Broadly speaking, there are two types of banishment systems, namely individual spiral and twin screw extruder systems. As the names imply, individual spiral extruders cover anelongated butt with alone a single, elongated, helically flighted, axially rotatable spiral accumulation therein. In contrast, accompanying twin screw extruder accept distinctively configured barrels with a brace of juxtaposed, helically flighted, axially rotatable andintercalated spiral assemblies. It is aswell absolutely accepted to apply a preconditioning accessory upstream of a individual or twin screw extruder, which serves to at atomic partially baker the starting abstracts and gelatinized the starch-bearing accoutrement thereof. Normally, college levels of baker and gelatinization are adapted inasmuch as this lessens affable requirements in the after extruder, arch to college superior articles and added throughputs.

It will added be apparent in FIG. 11 that the spiral sections 66a upstream of accumulation 32a are configured inthe address of ahead declared spiral sections 66, i.e., anniversary of the area 66a includes alternating, adverse angle spiral locations 82a-92a.

Thus, the accumulation 32a has a brace ofshearlock elements 94a, anniversary appropriately army on one of the hexagonal spiral shafts 76a. Also, a brace of against brake accoutrement 110a, 112a are provided, finer army in a vertical orientation, as shown. The close operating surfaces116a of the accoutrement 110a,112a accept a brace of abutting arcuate regions so as to accompanying board and appoint both of the shearlock elements 94a. In this embodiment, the drive accoutrement 132a is somewhat different. Specifically, the drivescrews 134a, 136a of the corresponding accoutrement 110a, 112a are accustomed aural a angled drive apartment 166 presenting spaced afar bores 168, 170. The axial sections of drive screws 134a, 136a amid the bores 168, 170 is able with a drive nut172. Adjustment of the accoutrement 110a, 112a is accomplished by circling of the drive basics 172, thereby confined to move the associated accoutrement 110a, 112a against and abroad from the shearlock aspect 94a. From the above discussion, it will be readilyappreciated that the accoutrement 110a, 112a move forth about accumbent and boxlike paths against and abroad from the shearlock elements 94a, aloft circling of the drive screws 134a,136a.
