Description

Feeding seat

Technical Field

The utility model relates to a subassembly technical field of rubber extruder and feeding machine, concretely relates to feed seat.

Background

At present, the feeding seat is widely used on processing equipment of products such as chemical industry, building materials, light industry, food and the like; the feeding seat as an important component of the feeding machine is decisive for the normal operation of the feeding machine.

The feeding seat in the prior art generally realizes feeding action through synchronous rotation of a side compression roller and a screw, and particularly can be seen in the feeding seat disclosed by publication number CN102862281B in publication date 2015, 03, 11, the background technology of the patent discloses that the feeding seat in the prior art comprises a feeding hole, a seat body, a screw mounting hole, a hinge, a first shaft sleeve, a first oil seal, a guide chute, a bearing cover pressing plate, a roller body, a driven gear, a second oil seal, a second shaft sleeve, a mounting seat, a driving gear mounting hole, a first bearing cover, a second bearing cover and a side compression roller mounting seat; the feeding port is positioned on the side wall of the seat body, a screw rod mounting hole penetrates through the seat body along the horizontal axial direction, a driving gear is in circumferential limiting fit on the screw rod, the driving gear is positioned in the driving gear mounting hole, a side compression roller mounting seat is hinged with the seat body through a hinge, the screw rod is mounted in the screw rod mounting hole, a roller body of the side compression roller abuts against the screw rod, rotating shafts respectively extend from the left end and the right end of the roller body, a first shaft sleeve, a first bearing and a bearing cover are sleeved on the rotating shaft at the left end of the roller body, a first oil seal is further arranged between the first shaft sleeve and the first bearing, a second shaft sleeve, a second bearing and a driven gear are sleeved on the rotating shaft at the right end of the roller body, and a second bearing cover is further sleeved on the peripheries of the second shaft sleeve and the second bearing, the left end face of second shaft sleeve and the left end face of second bearing cover all offset with the right-hand member face of roll body, be equipped with the second oil blanket between second shaft sleeve and the second bearing, driven gear and the spacing cooperation of the right-hand member pivot circumference of roll body, driven gear and driving gear direct meshing, the feed seat of this kind of structure is at concrete during operation, it rotates to take the driving gear to go through the motor, the driving gear drives screw rod and driven gear rotation again, driven gear and then drives other compression roller and rotate, realize the synchronous rotation of other compression roller and screw rod, because the roll body of other compression roller leans on with the screw rod counterbalance and the feed inlet just sets up in this department of leaning on, the material receives in the thread clearance of screw rod that the extrusion of other compression roller enters into, then under the rotatory propulsion of screw rod, the material moves forward.

However, the feeding base with such a structure has the following problems in practical use: when the material is extruded by the side press rolls, most of the material is pressed into the thread clearance of the screw, but partial materials enter the shaft sleeve and the bearing cover from the clearance between the left end and the right end of the roller body and the corresponding shaft sleeve and bearing cover respectively (the parts of the end surfaces of the left end and the right end of the roller body, which are abutted against the shaft sleeves, are smooth end surfaces, the left end surface of the roller body is abutted against the right end surface of the first shaft sleeve, the first shaft sleeve cannot rotate, the roller body rotates in the working process of the feeding seat, so that the left end surface of the roller body and the right end surface of the first shaft sleeve can move relatively, a tiny clearance can naturally exist, and similarly, a tiny clearance also exists between the right end surface of the roller body and the left end surface of the second shaft sleeve), moreover, the more the part of the materials are accumulated in the shaft sleeve, the rotation of the roller body can be influenced after a long time, and when the materials are rubber and the like, the influence of the leakage on the normal work of the roller body is very large; in order to solve the technical problem, one scheme adopted in the prior art is that a spiral guide chute is arranged on a first shaft sleeve and a second shaft sleeve, one end of the guide chute is connected with the end face of a roller body, and the other end of the guide chute extends from the shaft sleeve to the outside of a bearing cover, so that although a channel is provided for rubber leaking into the shaft sleeve, in the practical use process, the rubber leakage process is very slow, the rubber viscosity is very high, the rubber is difficult to smoothly lead out from the guide chute, and finally the rubber leaking into the shaft sleeve slowly accumulates and hardens to make the rotation of the roller body difficult; in conclusion, the feeding seat in the prior art has the problem of serious material leakage.
