The reason is that the feeding operation method is Short commissioning is manual commissioning based on feeling, the accuracy is not high, and can not meet the needs of masks of different specifications. At the same time, a lot of raw materials, time and manpower will be wasted during the commissioning process, which is very inconvenient to use.

【Utility Model Content】

The technical problem solved by the utility model is to overcome the traditional mask machine's tedious debugging process for the length of the nose bridge, which is manually debugged by the sense, the accuracy is not high, and it can not meet the needs of masks of different specifications. The problem of wasting a lot of raw materials, time and manpower.

In order to solve the above technical problems, the technical scheme adopted by the utility model is:

A nose bridge length adjusting device for a mask machine is characterized by comprising left and right symmetrically arranged on a first plastic transmission wheel bracket and a second plastic transmission wheel bracket, the first plastic transmission wheel bracket and the second plastic The transmission wheel bracket is provided with a plastic transmission wheel. The plastic transmission wheel is nested on the rotating shaft of the plastic transmission wheel. Both ends of the rotating shaft of the plastic transmission wheel are respectively embedded in the plastic transmission wheel bracket and the second plastic transmission wheel bracket. In the mounting hole of the rotating shaft, a vertical connection plate is fixed between the first plastic transmission wheel bracket and the second plastic transmission wheel bracket, and the top of the connection plate is provided with the first plastic transmission wheel bracket and the second plastic A fixing plate parallel to the transfer wheel bracket, a spring is arranged on the upper surface of the fixing plate, one end of the spring is embedded in the fixing plate, a plastic wheel is arranged under the fixing plate, and the plastic wheel is nested in the nose beam On the gear transmission shaft, the end of the nose bridge gear transmission shaft is connected to the nose bridge transmission transmission gear, and the plastic transmission wheel is located below the plastic wheel,

A main nose bridge debugging wheel and an auxiliary nose bridge debugging wheel are also provided below the plastic transmission wheel, the main nose bridge debugging wheel and the auxiliary nose bridge debugging wheel are of an eccentric structure, and the main nose bridge debugging The wheel and the auxiliary nose bridge debugging wheel are nested together on the nose bridge debugging wheel drive shaft, the end of the nose bridge debugging wheel drive shaft is connected to the nose bridge debugging wheel drive gear, and the nose bridge debugging wheel drive gear drives the nose bridge The driving shaft of the debugging wheel rotates to drive the main nose bridge debugging wheel and the auxiliary nose bridge debugging wheel to rotate. The main nose bridge debugging wheel and the auxiliary nose bridge debugging wheel rotate to realize the plastic transmission wheel to rise or fall, and the plastic transmission wheel to rise Or lower to push the plastic wheel to rotate or stand still. The rotation of the plastic wheel drives the nose bridge gear drive shaft to rotate or stand still. The nose bridge gear drive shaft drives the nose bridge delivery drive gear to rotate or stand still to realize transmission or stop transmission of the nose bridge bar.

The aforementioned nose bridge length adjustment device for a mask machine is characterized in that a bracket fixing shaft is also connected between the first plastic transmission wheel bracket and the second plastic transmission wheel bracket.

The aforementioned nose bridge length adjustment device for a mask machine is characterized in that the main nose bridge adjustment wheel and the auxiliary nose bridge adjustment wheel both adopt an eccentric wheel with a fan-shaped cross section, and the fan-shaped angle is 70°.

The aforementioned nose bridge length adjusting device for a mask machine is characterized in that: the end surface of the auxiliary nose bridge debugging wheel and the main nose bridge debugging wheel is provided with an angle line.

The beneficial effects of the utility model are: the nose bridge length adjusting device for a mask machine of the utility model is provided with an eccentric structure main nose bridge debugging wheel and an auxiliary nose bridge debugging wheel, which can drive the plastic transmission wheel to rise or fall when rotating It is used to adjust and adjust the length of the nose bridge, accurate control, prevent the generation of waste materials, save time and effort, greatly improve the production efficiency of the nose bridge, the structure is simple, and it has good application prospects.
