Multi-cutter plate continuous automatic hole opening device

Abstract

The invention provides a multi-cutter-head continuous and automatic hole opening device for plates. The multi-cutter-head continuous and automatic hole opening device comprises a frame and a plurality of hole opening machine heads, wherein each hole opening machine head comprises a power mechanism, a speed change mechanism and a hole opening mechanism; and an installation platform and two supporting frames are arranged on the frame, a pressing plate and a conveying belt are arranged on the inner side of the upper part of the supporting frame, a guide groove is formed between the pressing plate and the conveying belt; the speed change mechanism comprises a hollow shaft, a cam plate and a speed change assembly, and the hole opening mechanism comprises a rotary sleeve, a telescopic shaft and a cutter. Power is introduced into the speed change mechanism by virtue of the hollow shaft, and the power introduced by the hollow shaft can enable the rotary sleeve in the hole opening mechanism to be subjected to variable speed rotation under the matching effects of the cam plate and the speed change assembly so as to ensure that impulse type cutting can be performed by the cutter, the phenomenon of idle rotation of the cutter can be reduced, cutter feeding operations can be completed in a rotation process of the cutter, opening holes with cone-shaped surfaces can be formed in the plates, and the purposes of improving the finished product rate, reducing the labor intensity of workers and improving the processing efficiency can be achieved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a continuous automatic hole-drilling device with multiple cutter heads. Background technique [0002] At present, the drilling process for boards (wooden boards, plastic boards or stone boards) is usually performed by manual hand-held electric drills. When it is necessary to process a hole with a tapered surface for a plate with special requirements, the worker can only drill a small hole first, and then expand the surface to form a hole with a tapered surface. For processing, the labor intensity of the workers is relatively high, and, in the process of drilling, when the groove is formed on the plate, since the rotational speed of the drill bit remains constant, it is easy to appear that the drill bit is idling in the groove, and it takes a lot of time. to complete. It can be seen from the above that in the prior art, during the drilling operation of the plate, the labor intensity of ...

[0002] At present, the drilling process for boards (wooden boards, plastic boards or stone boards) is usually performed by manual hand-held electric drills. When it is necessary to process a hole with a tapered surface for a plate with special requirements, the worker can only drill a small hole first, and then expand the surface to form a hole with a tapered surface. For processing, the labor intensity of the workers is relatively high, and, in the process of drilling, when the groove is formed on the plate, since the rotational speed of the drill bit remains constant, it is easy to appear that the drill bit is idling in the groove, and it takes a lot of time. to complete

It can be seen from the above that in the prior art, the labor intensity of the workers is relatively high and the drilling efficiency is low during the operation of plate drilling.
