Vacuum-extruder extrusion device
Technical field
The utility model relates to a kind of extrusion device, is specifically related to a kind of extrusion device that is applied to vacuum-extruder, belongs to brick and tile production equipment technical field.
Background technology
Double-stage vacuum extruding machine is in current brick-tile industry, to use the most general brick equipment, mainly higher level's unit and subordinate's unit, consists of.Wherein in subordinate's unit, pug is in blanking port enters material receiving box, then by material receiving box extrusion molding.Existing subordinate material receiving box mainly adopts auger that pug is advanced to forming machine mouth, and auger only has screw propulsion effect, does not have degassing function.In actual production, the pug that pug falls in material receiving box after higher level's unit vacuumizes still contains the gases such as part air, at formative stage, due to swollen the rising of effect meeting of pressure, easily causes product crackle or cracking.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: a kind of vacuum-extruder extrusion device is provided, further by the Bas Discharged in pug, improves pug vacuum, improve the quality of products and yield rate.
Vacuum-extruder extrusion device described in the utility model, comprises material receiving box, in material receiving box, installs and extrudes axle, extrudes the anterior blade of installing of axle, extrudes axle rear portion helical blade is installed.
Extrude the blanking port side in the anterior corresponding material receiving box of axle, pug is in blanking port enters material receiving box, under the stirring action of blade, pug is again broken, and the gas containing in former pug is overflowed, and is discharged by vaccum-pumping equipment, the vacuum of pug improves again, molding blank is more closely knit, and product is not easy to crack, improves the quality of products and yield rate.
Described blade is arranged in pairs in extrudes axle both sides.
Described blade at least arranges one group, and blade magnitude setting can be determined according to actual conditions, as in areas such as plateaus, can arrange more group with better gas clean-up, and for the environment easily vacuumizing, can suitably reduce blade quantity.
Described helical blade vertically pitch not etc., helical blade is not by blanking port to discharging opening direction, pitch reduces gradually or reduces stage by stage, to improve pug to the propelling dynamics of forming machine mouth, reduces power consumption.
The course of work:
Pug, is extruded axle and is rotated under drive unit drives by higher level's unit in blanking port enters material receiving box, and the blade of rotation is smashed stirring again to the pug falling into, and the gases such as air that contain in former pug are overflowed in whipping process, through vacuumizing discharge.Pug after smashing is pushed ahead under continuous helical blade effect, and finally by discharging opening, enters the extrusion molding of forming machine mouth.
Compared with prior art, the beneficial effect that the utility model has is:
This vacuum-extruder extrusion device makes pug carry out fragmentation again by increasing blade, has improved pug vacuum, avoids product cracking, improves the quality of products and yield rate; The helical blade of varying pitch improves pug to the propelling dynamics of forming machine mouth, reduces power consumption.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Fig. 1~2, this vacuum-extruder extrusion device, comprises material receiving box 3, material receiving box 3 front portions arrange blanking port 1, axle 5 is extruded in the interior installation of material receiving box 3, extrudes the anterior blade 2 of installing of axle 5, and blade 2 is arranged in pairs in extrudes axle 5 both sides, and at least arrange one group, its quantity can be determined according to actual conditions, as in areas such as plateaus, can arrange more group with better gas clean-up, and for the environment easily vacuumizing, can suitably reduce blade 2 quantity.Extrude axle 5 rear portions continuous helical blade 4 is installed, helical blade 4 vertically by blanking port to discharging opening direction, pitch reduces gradually or is divided into pitch two ends not etc., the pitch of its posterior segment is less than leading portion, the helical blade 4 of varying pitch can improve pug to the propelling dynamics of forming machine mouth, reduces power consumption.
The course of work:
Pug by higher level's unit in blanking port 1 enters material receiving box 3, extrude axle 5 rotates under drive unit drives, 2 pairs of pugs that fall into of blade of rotation are smashed stirring again, and the gases such as air that contain in former pug are overflowed in whipping process, through vacuumizing discharge.Pug after smashing is pushed ahead under 4 effects of continuous helical blade, and finally by discharging opening 6, enters the extrusion molding of forming machine mouth.
