Abstract
The utility model relates to machining equipment, in particular to a device for grinding a rotary moving knife of a crusher, comprising double guide rails; one end of each guide rail is provided with a driving chain wheel; a grinding wheel which can slide along the guide rails under the dynamic action is arranged on one guide rail; a middle towing plate and a large towing plate which are used for adjusting the grinding wheel to move along the direction of the guide rail and the direction vertical to the guide rail are arranged at the corresponding positions of the other guide rail and the grinding wheel; and one side of each guide rail, which is close to the grinding wheel, is provided with a sliding bearing seat which has the same height with the center of the grinding wheel and can clamp the rotary moving knife, and a shaft head of the rotary moving knife is provided with a driven chain wheel which is connected with the driving chain wheel by a chain. In the device, the structure is simple, the technical requirements for maintaining and producing the equipment are met and the cost is saved.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically is a kind of device of reconditioning pulverizer revolution moving knife.
Background technology
Pulverizer revolution moving knife can produce tipping and blade wear phenomenon because of multiple reason after use a period of time.This not only makes the pulverizer resistance increase, and directly threatens the normal operation of pulverizer, but also can influence the ordinary production of PVA product quality and system.Therefore, in a single day tipping or blade wearing and tearing take place in the revolution moving knife, then must carry out reconditioning, to recover its function at once.
At present, flying knife generally uses large-scale cylindrical grinder to repair, the rehabilitation cost height, and be difficult to satisfy the production needs.
Summary of the invention
The purpose of this utility model is, at the deficiencies in the prior art, provides a kind of device of reconditioning pulverizer revolution moving knife, can satisfy the production needs, and expense is low.
Content of the present utility model, a kind of device of reconditioning pulverizer revolution moving knife, comprise two guide rails, at two guide rail one ends drive sprocket is housed, it is characterized in that, being provided with on a guide rail can be at the emery wheel of dynamic action lower edge guide rail slip, be provided with in another guide rail and described emery wheel relevant position and regulate middle carriage and the saddle that emery wheel moves along guide rail direction and vertical guide rail direction, but be provided with the plain bearing housing that turns round moving knife with the clamping of the same height in emery wheel center near emery wheel one side at described pair of guide rail, be equipped with by movable sprocket on the described back rotation cutter shaft head, and link to each other by chain with described drive sprocket.
Also comprise the grinding carriage that links to each other with emery wheel, this grinding carriage is fixed on described middle carriage and the saddle, and links to each other with power set and to drive emery wheel and move.
In order to reduce investment, can on the basis of existing lathe, acquire the function of necessary frock and certain part of change, change lathe upper slide rest and knife rest into part of the grinding head, realize horizontal, the lengthwise movement of emery wheel respectively by lathe middle carriage, saddle, load onto respectively on lathe chuck and the back rotation cutter shaft head main, by movable sprocket, the power of lathe spindle reaches the revolution moving knife, realizes the grinding circumferential movement of workpiece.
As known from the above, the utility model is as a kind of reconditioning pulverizer back rotation knife system, and is simple in structure, satisfies maintenance of equipment and manufacturing requirements, saves cost.
Description of drawings
Fig. 1 is a kind of example structure figure of the utility model.
The specific embodiment
As shown in Figure 1, at two guide rail 1 one ends drive sprocket 2 is housed, being provided with on a guide rail of two guide rails 1 can be at the emery wheel 3 of dynamic action lower edge guide rail slip, on another guide rail and emery wheel 3 relevant positions, be provided with and regulate middle carriage 4 and the saddle 5 that emery wheel 3 moves along guide rail direction and vertical guide rail direction, but be provided with the plain bearing housing 7 that turns round moving knife 6 with the clamping of the same height in emery wheel 3 centers near emery wheel 3 one sides at two guide rails 1, be equipped with by movable sprocket 8 on revolution moving knife 6 spindle noses, and link to each other by chain 9 with drive sprocket 2, grinding carriage 10 links to each other with emery wheel 3, this grinding carriage 10 is fixed on middle carriage 4 and the saddle 5, and link to each other with power set, drive emery wheel 3 and move.
