Technical Field

The invention relates to the technical field of tying devices, in particular to a fastener conveying device for a tying machine.

Background

The tying machine is the most widely used machine in the bag packaging industry, the aluminum button is sent into the bayonet by the button feeder, and the hinge pushed by the motor pushes the aluminum button to the bottom film when being closed, so as to tie the bag mouth. In the existing equipment, an aluminum buckle frame is arranged at the top of a panel, and an aluminum buckle in the aluminum buckle frame falls freely to achieve the purpose of buckle conveying. However, in the feeding mode, no external forward power is provided, so long as the aluminum buckle meets a little resistance in the falling process, the whole aluminum buckle strip is blocked, the tying process is interrupted, and the tying efficiency is influenced; and the feeding amount of the aluminum buttons cannot be controlled by the feeding mode, the situation that two or three aluminum buttons are tied on one bag body also happens occasionally, materials are wasted, and the production cost is increased.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the buckle conveying device for the tying machine, which has the advantages of simple structure, convenient operation and good buckle conveying effect.

In order to achieve the above purpose, the technical solution of the invention is as follows: the utility model provides a prick a mouthful machine and send knot ware, includes the base, its characterized in that: the utility model discloses a material pushing device, including base, left stand and right stand, but the aluminium knot pusher is provided with the guide pulley of free rotation, but the aluminium knot pusher is provided with aluminium knot pusher on the left stand, aluminium knot pusher is including can drive aluminium knot gyro wheel mechanism and the moving board device of dialling of control gyro wheel mechanism that advances.

The roller mechanism comprises a front vertical plate, a rear vertical plate, a cross shaft and rollers, wherein the front vertical plate and the rear vertical plate are arranged on two sides of the left stand column in a row, the middle parts of the front vertical plate and the rear vertical plate are connected with the left stand column through a rotating shaft, two ends of the cross shaft are connected with the top parts of the front vertical plate and the rear vertical plate through connecting nuts, the rollers are sleeved on the cross shaft, a one-way bearing is sleeved on the cross shaft, and the plate shifting device is fixedly connected with the cross shaft.

The plate shifting device comprises a shifting plate and a return spring, the shifting plate is sleeved on the cross shaft, one end of the shifting plate is a shifting handle, and the other end of the shifting plate is fixedly connected with the front vertical plate through the return spring.

The tail ends of the front vertical plate and the rear vertical plate are connected together through a connecting shaft, and the connecting shaft and the left upright post are connected together through a pressure spring.

Compared with the prior art, the invention has the following advantages:

1. the aluminum buckle is driven by the roller to rotate on the transverse shaft, and the aluminum buckle can smoothly descend even if the roller is slightly obstructed due to the driving of the roller, so that the jamming risk of the aluminum buckle strip is reduced, and the aluminum buckle can only move forwards but not move backwards due to the unidirectional bearing on the transverse shaft; dial the board by return spring control and stir once can only advance an aluminium and detain, dial the back return at once, such design not only can avoid a plurality of aluminium to detain the raw materials waste that the unloading caused simultaneously, and stylized action also makes the operation more simple and convenient.

2. The aluminum buckle pushing device is connected with the left upright post by the pressure spring, so that the aluminum buckle pushing device can continuously apply pressure to the aluminum buckle in the channel during buckle feeding, the aluminum buckle is prevented from sliding down in an accelerated manner, the broken roller mechanism can be supported during aluminum buckle installation, and feeding is facilitated.

3. The invention has simple structure, long service life and no need of electricity and gas supply, and can be installed on electric and manual tying machines.
