Abstract

The utility model relates to a counter weight lifting device for a packaging machine. The counter weight lifting device comprises a connecting frame, wherein transparent covers are connected to the two ends of the connecting frame; the two ends of each transparent cover are connected with brackets; each bracket is connected with a pressing plate through connecting bolts; a V-shaped roller is connected into a hole between each bracket and the corresponding pressing plate through a pin shaft. The V-shaped rollers are arranged on a counter weight lifting mechanism; in ascending and descending processes of a counter weight, the V-shaped rollers vertically roll along square vertical columns, so that the problem of friction between original V-shaped sliding plates and vertical columns is thoroughly solved, the service life of each vertical column is prolonged, the usage cycle of each vertical column is greatly prolonged, the maintenance cost of the packaging machine is reduced, the labor intensity of a maintainer is reduced, and the production efficiency is improved.

Description

A kind of compress weight bont

Technical field

The utility model belongs to wire rod compress technical field, particularly a kind of compress weight bont.

Background technology

Before along with the improving constantly of machinery production degree of automation, various compresses are widely used in product line.In Steel-rolling Industry, the wire rod of having produced generally installs around into package product by compress and transports and sell.Compress is to drive by the wire agency with HM Hydraulic Motor on platen in packing process, then sends into lead frame and return, and by wire agency, completes line sending, take-up and tension, and receives disconnected kink by packing head, thereby completes the overall process of packing.

In packing process, first the platen relative motion at compress two ends compresses wire rod, cylinder on compress line taking platform on swelling device stretches out the fabric wheel driving on cranking arm pack thread is compressed along with wire agency line sending weight promotes, after after packing completes, platen resets, weight bont rests in midair, at this moment the fabric wheel that the cylinder on the swelling device on compress line taking platform resets on cranking arm is opened, and weight bont relies on deadweight freely to fall, thereby completes the overall process of packing.

What original weight bont adopted is a kind of V-type slide plate design (see figure 1), on every cover weight bont, be provided with 4, its radical function is along in column ascending and descending process at weight bont, weight plays location and guide support effect, because causing column and V-type slide plate, column and the long-time up-and-down movement friction of V-type slide plate generally using about 1 year just because frictional failure seriously must be changed, because column design length is 6m vertical lifting again, change abnormally dangerous and trouble.

Summary of the invention

The utility model for solve the technical matters existing in known technology provide a kind of simple in structure, operating cycles is long, and can effectively reduce compress repair and maintenance expense, the compress weight bont of raising compress work efficiency.

The technical scheme that the utility model is taked for the technical matters existing in solution known technology is:

A kind of compress weight bont, comprise link span, the two ends of described link span are connected with transparent cover, and the two ends of described transparent cover are connected with support, described support is connected with pressing plate by tie bolt, in the hole between described support and pressing plate, by bearing pin, connects V-arrangement running roller.

Described V-arrangement running roller inside is provided with 2 bearings.

Advantage and the good effect that the utlity model has are:

V-arrangement running roller is installed on heavy hammer lift mechanism, in weight rising and decline operational process, V-type running roller has thoroughly solved the friction problem between original V-type slide plate and column along square column scroll-up/down, extended the service life of column, the operating cycles of column is significantly improved, not only reduce the inspection and maintenance expense of compress, also reduced the labour intensity of maintenance man, improved production efficiency simultaneously.

Accompanying drawing explanation

Fig. 1 is weight bont perspective view before improving;

Fig. 2 is the utility model perspective view;

Fig. 3 is Fig. 2 lateral plan.

In Fig. 1, Fig. 2 and Fig. 3,1.V shape running roller, 2. transparent cover, 3. tie bolt, 4. pressing plate, 5. support, 6. link span, 7. column, 8.V shape slide plate.

The specific embodiment;

For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 2 and Fig. 3, a kind of compress weight bont, bag link span 6 and V-arrangement running roller 1, the two ends that connect frame 6 are connected with transparent cover 2, the two ends of transparent cover 2 are connected with support 5, support 5 is connected with pressing plate 4 by tie bolt 3, in the hole between support 5 and pressing plate 4, by bearing pin, V-arrangement running roller 1 is installed, and V-arrangement running roller 1 inside is also provided with 2 bearings.

V-arrangement running roller is installed on heavy hammer lift mechanism, in weight rising and decline operational process, V-type running roller 1 has thoroughly solved original V-type slide plate 8(along square column 7 scroll-up/down and has seen Fig. 1) and column 7 between friction problem, extended the service life of column 7, the operating cycles of column 7 is significantly improved, not only reduce the inspection and maintenance expense of compress, also reduced the labour intensity of maintenance man, improved production efficiency simultaneously.

Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belong to protection domain of the present utility model.
