Description

Grinding devices for folder gluers and folder gluers

technical field

The utility model belongs to the technical field of packaging machinery manufacturing, relates to post-processing equipment for packaging machinery producing cardboard and cartons, and is used in the box-gluing equipment for feeding, grinding, gluing, folding and pressing formed cardboards. The grinding part is specifically a grinding device for a folder gluer and a folder gluer.

Background technique

The process flow of the box gluer and folder gluer is: feeding, grinding, gluing, folding, pressing, and output. The main function is to apply glue to the bonding part of the cardboard, then fold it along the existing creasing line, and then stuff it into the pressing part. Since the cardboard has been coated and polished before entering the gluer and folder-gluer, if If you apply glue directly on the bonding part, you need to use a special adhesive, otherwise the bond will not be strong. The price of this special adhesive is high. In order to reduce the cost, the adhesive part is usually polished first, and the paper coating and glazing surface are removed to expose the original paper surface, and then the glue is applied, so that the adhesive can Use white latex which is much less expensive.

At present, mechanical methods are mostly used for grinding the bonded parts of cardboard. The grinding tools are mostly milling blades and grinding wheels. The speed of the tool can generally reach more than 4000 rpm. The fan sucks it away, and the thickness of the grinding can be adjusted. The existing grinding mechanism mainly has problems such as difficult adjustment and incomplete dust collection.

Contents of the invention

The utility model aims at the problems and deficiencies of the prior art, and provides a box gluer and box gluer grinding device, which has a simple and compact structure, and can effectively grind the bonding parts of the cardboard to be glued. And the grinding thickness is easy to adjust, and the dust disposal is timely and thorough.

The purpose of this utility model is achieved by the following technical solutions:

A grinding device for box gluer and folder gluer, including a high-speed motor fixed on the machine frame, a synchronous belt and a pulley, a brush, a blade, an air box fixing seat, an air box on the air box fixing seat, a press The wheel is characterized in that: one end of the bottom of the wind box fixing seat is hinged with the frame to form a fulcrum, and the other end is located on an eccentric shaft, which is arranged on the frame and locked by the eccentric shaft locking device.

Improvement to the above technical solution: One side of an "L" shaped adjustment block is fixed on the upper plane of the wind box fixing base by screws, and the other side of the "L" shaped adjustment block is pressed on the upper plane of the wind box, "L" Thin gaskets are set between the shape adjustment block and the upper plane of the wind box fixing seat. The position of the wind box relative to the wind box fixing seat can be easily adjusted in small amounts.

A further improvement to the above technical solution: there is a detachable baffle strip on both sides of the hole reserved for the blade in the upper part of the wind box.

A further improvement to the above technical solution: the high-speed motor is installed under the frame, and the body of the high-speed motor faces inward.

Compared with the prior art, the utility model has the following advantages and positive effects:

1. The utility model adopts the special design of the eccentric shaft, which greatly improves the convenience of adjusting the position of the wind box and can better adapt to the bending of cardboard.

2. The design of the adjustment block and the thin gasket of the utility model facilitates micro-adjustment of the position of the air box after the blade is worn.

3. The detachable baffle strips on both sides of the tuyere of the air box of the utility model can adjust the width of the tuyere according to the number of blades installed, which is conducive to the downward suction of paper scraps and makes the vacuuming cleaner.

4. The motor of the utility model is installed under the frame, and the motor fuselage faces inward. Compact structure, small footprint, more convenient operation and adjustment, more in line with ergonomic requirements.
