Description

Machine head cutting device for strip extruding machine

Technical Field

The utility model relates to a aircraft nose blank device for plodder belongs to plodder technical field.

Background

Single screw rod, twin-screw, extruder such as plunger are when crowded strip, and the extrusion material often is rectangular form, but length overlength can fracture naturally, leads to material length different in size, and this is all unfavorable to transport, drying, packing etc. of follow-up material, sets up the eager grain alone and can cause the system flow too complicated, can increase cost, resource-wasting moreover.

Disclosure of Invention

The utility model discloses the technical problem that will solve lies in: the utility model provides a aircraft nose blank device for plodder, it has solved prior art's plodder extrusion material length and has differed too big problem, plays the effect of homogenization material length.

The utility model discloses the technical problem that will solve takes following technical scheme to realize:

a machine head cutting device for a bar extruding machine comprises a cutting device, wherein the cutting device comprises a rack, a variable frequency motor, a speed reducer, a driving main shaft, a coupler, a rotary cutter and a connecting flange;

the improved rotary cutting machine is characterized in that a connecting flange is arranged at one end of the frame, a variable frequency motor is installed at the other end of the frame and connected with a speed reducer, one end of the driving main shaft is connected to a rotating shaft of the speed reducer through a coupler, and a rotary cutter is fixed at the other end of the driving main shaft.

As a preferred example, the rack is further provided with a bearing system, the bearing system comprises a base, a roller bearing and a thrust bearing, one end of the base is fixed on the rack at one end close to the speed reduction motor, the roller bearing and the thrust bearing are arranged in the base, and the driving spindle sequentially penetrates through the roller bearing and the thrust bearing.

As a preferred example, two sets of roller bearings and one set of thrust bearings are provided in the base.

The utility model has the advantages that:

(1) the cutting device is directly arranged on a flange at the discharging end of the extruder through a connecting flange, a bolt and the like, and can also be independently arranged at the discharging end of the extruder, so that the problem that the extruding machine has too large difference in the length of extruded materials can be effectively solved, and the function of homogenizing the length of the materials is achieved;

(2) the stable operation of the driving main shaft is ensured by installing the bearing system on the frame of the cutting device.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained with reference to the following specific drawings and embodiments.

Example (b):

as shown in fig. 1, a machine head cutting device for a bar extruder comprises a cutting device, wherein the cutting device comprises a rack 1, a variable frequency motor, a speed reducer 2, a driving main shaft 3, a coupler 4, a rotary cutter 5 and a connecting flange 6; 1 one end of frame is equipped with flange 6, and the direct mount such as blank device accessible flange 6, bolt also can set up solitary device on crowded strip machine ejection of compact end flange, settles at crowded strip machine discharge end, can adjust as required with crowded strip machine ejection of compact template's distance. The variable frequency motor is installed to the frame 1 other end, and variable frequency motor is connected with

speed reducer

2, and 3 one end of drive main shaft is connected to the pivot of speed reducer 2 through shaft coupling 4, and the other end is fixed with rotary cutter 5.

The frame 1 is further provided with a bearing system, the bearing system is composed of a base 71, roller bearings 72 and a thrust bearing 73, one end of the base 71 is fixed on the frame 1 close to one end of the speed reducing motor, two groups of roller bearings 72 and one group of thrust bearing 73 are arranged in the base 71, and the driving spindle 3 sequentially penetrates through the roller bearings 72 and the thrust bearing 73. The bearing system effectively ensures the stable operation of the driving main shaft 3.

The blanking device is also provided with an electrical control system which comprises a frequency converter and a switch, the control operations such as rotating speed display and adjustment, emergency stop and the like can be realized according to the needs, and signals can be introduced into the PLC and the rotating speed linkage of the host machine.

The working principle is as follows:

the strip material after the material extruding machine extrudes is cut off by rotary cutter 5 of the cutting device at the position of a discharge template of the extruding machine, the length of the material after the material is cut into granules can be controlled by adjusting the rotating speed of the rotary cutter 5, and the distance between the rotary cutter 5 and the discharge template can be adjusted according to the physical property and the discharge condition of the material.
