technical field

The utility model relates to the field of material receiving machine equipment, in particular to a material discharging mechanism of a multi-head material receiving machine.

Background technique

At present, the wire arrangement mechanism of the known bare wire reflexing machine is to transmit the motion to a plurality of wire arranging rods with racks through multiple gears after the forward and reverse motors are decelerated, so that all the wire arranging rods realize synchronous reciprocating linear motion ;Generally there are cable rods arranged in pairs, and each pair of cable rods is connected by a guide wheel connecting piece. Multiple cable guide wheels can be installed on the guide wheel connecting piece. Orderly rows. However, there are following defects in this wire arrangement mechanism using a reduction mechanism and rack and rack transmission: 1. There are many stages of motion transmission. After the reduction mechanism, there is a first-stage bevel gear and a first-stage rack and pinion transmission. The meshing clearance of the shaft device will lengthen the pause time of the cable guide wheel when the motor changes direction, which is the main reason for the large amount of maintenance of the cable arrangement mechanism; The speed and distance of the linear motion of the wire rod may not be synchronized, resulting in the inability to adjust the wires of each axis synchronously. This is the main reason for the difficulty in adjusting the wire routing mechanism and the low accuracy of the wires; 3. Each wire rod has four Guide wheel guide, each pair of cable rods has eight guide wheels, the installation and adjustment of the guide wheels is based on the corresponding cable rods as a reference, lack of a unified benchmark, and there are cable rods connected between the cable rods, so often There is a phenomenon of mutual competition to accelerate wear, which will lead to frequent maintenance accidents. In a word, this kind of cable arrangement using variable speed transmission and rack and rack transmission has disadvantages such as low precision, poor synchronization, complicated transmission and difficult maintenance.

Utility model content

The purpose of this utility model product is to overcome the shortcomings of the existing wire arrangement mechanism using variable speed transmission and rack drive, and provide a multi-head material discharge mechanism with high precision, good synchronization, simple transmission and easy maintenance.

In order to achieve the above object, the utility model adopts the following technical solutions:

The discharge mechanism of the multi-head receiving machine includes a frame, a transmission motor, a screw rod, a screw nut connecting frame, and a wire rod; the transmission motor is connected with a screw rod, and the screw rod is connected with the screw nut. Connecting frames are connected vertically and horizontally, and the connecting frame is equipped with at least two cable rods in the longitudinal direction and horizontal direction respectively. ; The two ends of the horizontal cable rod are respectively connected with guide wheel connecting pieces, and each guide wheel connecting piece is provided with at least one cable guide wheel, and the frame is provided with a retractor driven by a low-speed motor corresponding to the cable guide wheel. spool.

Wherein the transmission motor is a low-speed synchronous motor.

Wherein the transmission motor is provided with a frequency converter.

The beneficial effect of the utility model is that: the mechanism of the utility model drives the screw rod through the transmission motor and then drives the screw nut to drive the wire arranging rod to move, and the wire arranging guide wheel on the wire arranging rod drives the winding wire to wind it on the take-up shaft. The above-mentioned structure makes the utility model have the characteristics of high precision, good synchronization, and a simple and easy-to-maintain structure that is not easy to wear.
