Compared with the common radial pin barrel cold feed extruder, the pin barrel cold feed extruder disclosed by the utility model has a better plasticizing mixing effect, lower extrusion temperature, higher production capacity and a wider application range.
Description
Technical field
The utility model belongs to rubber processing machinery equipment, particularly be a kind of pin barrel cold feed extruder.
Background technology
Radially the pin barrel cold feed extruder is since last century, the mid-1970s entered rubber processing industrial production field, because of having high output, it make cold feeding replace hot feeding to become a reality, and because its lower extrusion temperature and high superior combination properties such as homogeneity, obtain very extensive use at home and abroad in the rubber industry, and occupied the dominant position of modern rubber extrusion forming equipment.From being born to now, radially the technology of pin barrel cold feed extruder is just always in continuous development.Chinese patent " pin barrel cold feed rubber machine " (patent No. ZL94231236.8) provides between a kind of motor and the gear reduction unit and to have adopted the triangle strip transmission, other pressure roller left and right sides bearing bracket side is worn with the screw thread of other pressure roller switched in opposite return glue groove, pin barrel adopt can before and after the pin barrel cold feed extruder technology of the full symmetrical configuration installed of transposing, purpose is to reduce spatial volume, improve standardization level, reduce noise and prevent that other pressure roller two ends from leaking glue.
Chinese patent " the pin cooling structure of pin extruder " (patent No. ZL200320131569.9) provide a kind of pin cooling structure of pin barrel cold feed extruder.The pin that radially is provided with along screw rod has hollow chamber, by the logical circulating cooling liquid body of pipe in chamber, inserting, or by in chamber, directly adding phase-change material (as paraffin, dry ice), carry out the pin cooling, thereby, when extruding the processing sizing material, more effectively, under meeting the requirements prerequisite, extrusion temperature improves extrusion capacity to the cooling of sizing material mid portion.
Chinese patent " pin cold feed extruder " (patent No. ZL200920232372.1) provides a kind of radially pin length in machine barrel can regulate and respectively arrange the pin spacing by being threaded along extruding the technology that direction is successively decreased.Its objective is according to bipeltate and extrude the processing needs, effectively regulate control sizing material temperature, avoid sizing material " overheated " to cause sulfur foam in advance.
By above-mentioned patent as seen, the present radially technological development direction of pin barrel cold feed extruder mainly concentrates on drive system, other pressure roller drawing-in device and pin aspect.Although radially the pin barrel cold feed extruder has many excellent properties, because radially pin has limited plasticizing effect with sizing material contact length little (in the screw channel degree of depth); And the intrinsic high viscosity of sizing material can produce a large amount of frictional heats inevitably in extrusion, even radially pin has adopted cooling provision, because of its frigorimeter area is restricted.Therefore, for preventing to degrade with incipient scorch and considering that the upper limit of the processing temperature of sizing material own retrains, the maximum (top) speed of pin barrel cold feed extruder screw rod must limit, and can not further improve production capacity by increasing screw speed merely, and production capacity and economy reduce as a result.
The utility model content
Technical problem to be solved in the utility model just provides a kind of plasticizing mixed effect and the better pin barrel cold feed extruder of cooling effect, and it can significantly improve production capacity by further increase screw speed.
A kind of pin barrel cold feed extruder described in the utility model, comprise the machine barrel that is installed on the feeding pedestal, in machine barrel, be provided with screw rod, along the barrel length direction radially pin of plurality of rows is set, respectively radially pin is fixed on the machine barrel by the spiral pressure cap, the pin termination is stretched in the screw channel and near surface, screw rod root footpath, has to hold at the corresponding site of screw rod spiral shell rib and inserts the radially circumferential grooving of pin; It also is provided with the tangential pin of plurality of rows, described tangential pin passes the pin hole on the machine barrel, along screw rod tangentially pass screw channel, have at the corresponding site of screw rod spiral shell rib and hold the circumferential grooving that passes pin, tangential pin two ends are fixed on the machine barrel with nut by external screw thread.
As improvement of the present utility model, in tangential pin inside, be provided with cooling channels along whole length direction, tangential pin nails on and is provided with cooling channels import and outlet, is connected the outer circulation cooling device by import with outlet.
Above-mentioned every row's tangential pin can be cascaded by pipeline, and respectively arranges tangential pin and be divided into some groups, and every group is cascaded by pipeline respectively, and each group connects independently outer circulation cooling device.
As further improvement of the utility model, tangential pin can be provided with in pairs, and lays respectively at the both sides of machine barrel.Tangential pin is on the same cross section of machine barrel with radially pin is corresponding.The machine barrel cross section is preferably rectangle, is installed on the machine barrel with convenient tangential pin.
Pin of the present utility model arranges and is divided into two kinds, and a kind of is tangential arrangement along screw rod, and another kind is the arranged radially along screw rod; Tangential pin is a hollow structure, can through-flow body cooling medium; The tangential pin that has the hollow cooling structure by setting, the plasticizing that has not only strengthened sizing material mixes ability, and film-cooled heat and cooling effect have been increased greatly, can be when guaranteeing lower extrusion temperature and extruding quality uniformly, significantly improve production capacity by further increase screw speed, and the range of work is more extensive.
