Description

Multi-station rotary table and its method for drilling and planting

technical field

The invention relates to a brush manufacturing equipment, in particular to a multi-station rotary table; the invention also relates to a method for drilling and planting on a multi-station rotary table, which can be completed synchronously on the brush board. Material, drilling, hair planting and blanking belong to the technical field of brush processing equipment and processing methods.

Background technique

The tufting machine is widely used in drilling and tufting on brush bodies such as daily brushes and industrial brushes. For the processing of flat brushes, the drilling and planting worktable of the traditional tufting machine is located below, the brush plate of the flat brush is clamped on the drilling and planting workbench, and the length direction of the flat brush brush plate extends along the width direction of the drilling and planting workbench. The drilling and hair-planting surface of the flat brushing board faces upward, and the machine head is located above the drilling and planting workbench. The machine head is equipped with a drilling mechanism and a hair-planting mechanism. The rear side of the machine head is connected to the base, and the base extends downwards to The drilling and planting workbench is connected on a common base.

When the plane brush is relatively long, the machine head needs to protrude forward for a relatively long distance due to the wide drilling and planting workbench. The cantilever structure leads to a large volume and weight of the overall tufting machine, and the space above the drilling and planting workbench is drilled. Mechanism and tufting mechanism are occupied, and automatic loading and unloading devices cannot be arranged. The loading and unloading of brush plates are all completed by manual assistance, which is labor-intensive and has certain risks. Once the operator makes a mistake, such as failing to remove the brush plate that has been planted in time, it will cause interference between the planting nozzle and the brush plate, resulting in equipment damage.

After the synchronization is completed, switch. The first station uses the second and third stations to drill. The blanking of the finished brush plate and the loading of the new brush plate are completed at the time of hole and hair planting, and each station works synchronously without interfering with each other. Because each station is located on different phases, it is convenient to arrange drilling device, hair planting device and loading and unloading manipulator on the outside of each station respectively; For the drill bit and the tufting nozzle, the cantilever arrangement and transmission form of the drilling device and the tufting device are avoided, and the production efficiency is improved while reducing the overall weight of the equipment.
