Spliced paperboard sticking opening polishing device

Abstract

The invention discloses a splicing cardboard sticking mouth grinding device, which comprises a machine base, a grinding wheel frame and a driving device are installed on the machine base, a grinding wheel is arranged on the grinding wheel frame, and a pressure wheel and the grinding wheel are arranged directly above the grinding wheel. The grinding wheel is in contact with the driving device. The driving device is a geared motor with a deceleration mechanism. The output end is equipped with a synchronous wheel. There is a belt through hole on the base below the synchronous wheel. The synchronous wheel is synchronized with the driven wheel at the shaft end The wheels are connected by a synchronous belt, and the synchronous belt passes through the belt through hole; the top of the grinding wheel frame is equipped with a screw, and the screw is covered with a spring, and the screw is equipped with an adjustable wheel that can move up and down above the spring. block, a knob is installed above the adjustment block, the knob is threadedly connected to the screw rod, and its lower end surface is against the adjustment block, and the pressure wheel is connected and installed on the adjustment block. The device improves production efficiency and solves the problem of not sticking tightly due to residues.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a grinding device for cardboard roughening. Background technique [0002] In production, there are often some packaging cardboards that cannot be effectively utilized, so people often disassemble multiple cardboards for splicing so that they can be used where needed. Glue is generally used for bonding, and the bonding fastness is not good. It is high and cannot be tightly bonded, so when splicing cardboard, the sticky part must be roughened, but the existing bonding method is mainly to use manual grinding with sandpaper, which is not only slow and efficient, but also often has residues on the sticky part It is difficult to control the grinding position and grinding area, which will easily cause the grinding area to exceed the reserved sticking position and affect the appearance. Contents of the invention [0003] In order to overcome the deficiencies of the prior art...

Glue is generally used for bonding, and the bonding fastness is not good. It is high and cannot be tightly bonded, so when splicing cardboard, the sticky part must be roughened, but the existing bonding method is mainly to use manual grinding with sandpaper, which is not only slow and efficient, but also often has residues on the sticky part objects, resulting in poor adhesion when splicing cardboard, and it is difficult to control the grinding position and grinding area, which will easily cause the grinding area to exceed the reserved sticking position and affect the appearance
