Abstract

The utility model discloses a novel scraper device, which comprises: a scraper body, a plurality of scraper holders, scraper blades, a pressure tube and a pin; wherein the scraper body is connected with a dynamic device, the scraper blades is inserted in the scraper holder hinged with the pin, the hose shaped pressure tube locates between the scraper body and the scraper holder; the scraper body is in a roller shape, a triangle mounting rack welded by the steel plate is provided on the scraper body, each scraper holders is connected with a scraper blade support plate by a screw, and leans on the mounting rack. The scraper body of the utility model adopts large size roller body, and adopts the triangle mounting rack welded by the steel plate to mount the scraper rack, thereby the rigidity is very good, and the rigidity requirement used in the scraper device is ensured; the scraper device has simple structure, convenient manufacture, low cost and good rigidity, can adjust the tightness of the scraper to the drying cylinder surface, makes the scraper fully and effectively be applied on the drying cylinder surface, thereby improving the sheet tortuosity or cleaning effect and prolonging the service life of the scraper.

Description

Novel doctor blade device

Technical field:

The utility model relates to the paper making equipment technical field, especially relates to the doctor blade device that uses on a kind of paper machine.

Background technology:

On large-scale paper machine, scraper all is large span work.On the at present common dryer scraper device, separate scraper holder is subjected under the rigidity of structure influence in the scraper main body, and each scraper holder is the neither one homogeneity in height.Make that like this wing that is placed on the scraper holder is firmly uneven on whole dryer surface, the continuous service life of wing is short, and regular tool changing has reduced production efficiency, has increased the waste paper rate.

Practical content:

The purpose of this utility model is the weak point that exists at prior art and a kind of novel doctor blade device is provided that it has the characteristics of rigidity of structure height, the continuous long service life of scraper.

For achieving the above object, the utility model includes: scraper main body, a plurality of scraper holder, wing, pressure pipe, bearing pin; Wherein, the scraper main body links to each other with power set, wing be inserted in the hinged scraper holder of bearing pin in, the pressure pipe of hose-like is between scraper main body and scraper holder; Described scraper main body is the roller shape, has the triangle installing rack that steel plate is welded on it, and each scraper holder and a wing gripper shoe link together by screw, and lean against on the installing rack.

The roll body of described scraper main body is eccentric to be provided with.

Described scraper main body two ends are provided with the tool rest check plate.

The beneficial effects of the utility model are: the scraper main body adopts large-sized roller shape body, and the triangle installing rack installation doctor blade holder that adopts steel plate to be welded into, and rigidity is very good, has guaranteed doctor blade device rigidity requirement in use; Its structure is also comparatively simple, processing and fabricating is convenient, low, the good rigidly of cost, and can make the degree of being adjacent to of real-time adjustment scraper to dryer surface, and wing is fully effectively sticked on the drying cylinder face, thereby improve paper tortuosity or cleaning effect, prolong the service life of wing.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the partial enlarged drawing of Fig. 2;

Fig. 4 is the structural representation of scraper main body;

Fig. 5 is the assembling schematic diagram of the utility model in paper making equipment.

The specific embodiment:

The following stated is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See that Fig. 1 is to shown in Figure 5: the utility model includes scraper main body 10, a plurality of scraper holder 20, wing 30, pressure pipe 40, bearing pin 50, installing rack 60, wing gripper shoe 70, tool rest check plate 80.

Scraper main body 10 links to each other with power set, and integral body is the roller shape, can guarantee the radial rigidity of the wing strong point; Has the triangle installing rack 60 that is welded into by steel plate on the scraper main body 10, guaranteed the rigidity that scraper is tangential, make that wing 30 keeps making that near in a linear state job superincumbent scraper is installed has good stable when work, improved the service life of wing 30 greatly.In addition, roll body 11 eccentric settings the at scraper main body 10 middle parts can make scraper part and roll body partly reach static balance effectively, make scraper more stable at work, reduce the vibration that causes because of self structure, improved the quality of operating efficiency and paper production.

Wing 30 be inserted in the hinged scraper holder 20 of bearing pin 50 in, its bottom and scraper holder 20 interior top boards contact.

Each scraper holder 20 is spaced apart from each other and is separate, and can be around bearing pin 50 and scraper main body 10 rotations relatively, make the horizontal different parts of scraper to be close to dryer surface with constant compression force, thereby improve tortuosity and cleaning efficiency along with the fluctuating of dryer surface.

Scraper holder 20 and wing gripper shoe 70 link to each other by screw, make that the possibility that overcomes that is applied on the wing 30 is even, simultaneously, wing gripper shoe 70 plays a transition role between scraper holder 20 and wing 30, avoid scraper holder 20 directly power to be acted on the wing 30 with the form of point and the situation of wing discontinuity wing point fatigue damage occurred, realization acts on the wing with the form of linear pressure, makes wing 30 stressed even, increases the service life;

The pressure pipe 40 of hose-like is between scraper main body 10 and scraper holder 20, be full of the gas of certain pressure intensity in the pressure pipe 40, be used for each scraper holder 20 is pushed up outward, when dryer surface rises and falls, under the pressure effect of pressure pipe 40, scraper holder 20 is rotated around bearing pin 50 respectively, by leverage effects compressing wing 30, make wing 30 each position all be close to dryer surface, and can adjust the power that each scraper holder 20 acts on dryer surface with the fluctuating of dryer surface with constant compression force.

Tool rest check plate 80 is arranged on scraper main body 10 two ends, can make trying hard to keep of 30 pairs of drying cylinders of wing be held in the restricted portion or the activity of scraper holder 20 remains in the scope by regulating adjusting bolt on it.

In addition, the horizontal level of the installation shaft bearing of doctor blade device can be finely tuned by the bolt on the installing rack 11, thereby guarantee wing 30 can with the tangent line of dryer surface at an angle, as calculated and facts have proved, when wing 30 and dryer surface contact point tangent line are a special angle, the operating efficiency of scraper is best, and service life is also the longest.
