Plate Continuous Automatic Hole Opening Device

Abstract

The invention discloses a continuous automatic punching device of a panel. The continuous automatic punching device comprises a rack, a power mechanism, a speed changing mechanism and a punching mechanism, wherein a mounting platform and two support frames are arranged on the rack, a pressing plate and a conveyor belt are arranged at inner sides of upper parts of the support frames, a guide groove is formed between the pressing plate and the conveyor belt, the speed changing mechanism comprises a hollow shaft, a cam plate and a speed changing assembly, and the punching mechanism comprises a rotary sleeve, a telescopic shaft and a cutter. A power is introduced into the speed changing mechanism by virtue of the hollow shaft, the power introduced by the hollow shaft can ensure that the rotary sleeve in the punching mechanism rotates in a speed changing manner under a matching function of the cam plate and the speed changing assembly, so that the cutter can form pulse cutting, the idle rotation of the cutter is reduced, the feed action is completed by the cutter in a rotating process, a pore with a conical surface can be formed in the panel, the increase of the yield of the continuous automatic punching device of the panel is realized, the labor intensity of a worker is reduced, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a continuous automatic hole-drilling device for plates. 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 the workers is r...

[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.
