Splashing prevention plate perforating device

Abstract

The invention discloses a splash-proof sheet material punching device, which comprises a frame, an operating table and a motor on the frame, the motor is connected with a first gear, the first gear meshes with a second gear, and there is a negative pressure in the sealed shell. The vane, the negative pressure vane is coaxially connected with the second gear, the sealing shell has a liquid inlet and a liquid outlet, the first gear is connected with a cylinder, the cylinder is connected with a turntable, the turntable is connected with a drill bit, and the turntable is sleeved with a shaft sleeve. There is a third gear that rotates, and the third gear meshes with an internal gear. The internal gear and the internal gear are fixed on the inner side of the sleeve. The inside of the sleeve is hollow, and the sleeve has a number of water curtain holes. There is a water tank on the console, and the water tank is connected to the liquid inlet. , the liquid outlet is connected with the shaft sleeve, and the two sides of the annular groove are connected with hollow pipes, and the hollow pipes are connected with the water tank. A spring is connected; compared with the prior art, the present invention can prevent waste chips from splashing and hurting people during the process of punching a plate.

Description

technical field [0001] The invention relates to the field of furniture processing, in particular to an anti-splash board punching device. Background technique [0002] Sofas, recliners, etc. are commonly used furniture in people's lives. These furniture are composed of plates and fillers installed on the plates. The plates need to be drilled on the plates for subsequent connection and fixation with bolts and other fixing parts; the application number is 201010613582.2 The patent document disclosed a drilling machine, including a motor and a machine needle, the needle is equipped with a point heating device, and the point heating device is gradually heated by radiation; although this drilling machine can complete the drilling of the plate , but when it is necessary to open holes of different diameters on the plate, it is necessary to manually replace the drill bit according to the size of the hole to be opened on the plate, which is very inconvenient to use. [0003] In orde...

AI Technical Summary

Problems solved by technology

[0004] This punching device can easily replace the drill bit, but there is also the following problem: the anti-chip board is only installed on one orientation of the drilling device, and in the process of drilling the plate, the operator does not install the anti-dusting board on the drilling device. When the orientation of the chip board is changed, the waste chips will splash around and easily injure the operator
