The paper web static eraser
One, technical field
The utility model relates to a kind of page static of eliminating, and reduces the device that foreign matter absorption causes paper defects, the paper web static eraser in specifically a kind of paper-making process.
Two, technical background
In the present paper industry, can produce a large amount of static, after the paper web that has a large amount of static enters calender, then can adsorb paper powder and paper scrap and enter nip, form paper defects at back segment at hard calender place, particularly, even more important for the massey paper machine.In existing paper-making process, at hard calender place static eraser is not set, be difficult to avoid paper web enter behind the calender can absorption paper powder and paper scrap enter nip, form paper defects at back segment, cause papery to descend, substandard product appears.
Three, summary of the invention
The purpose of this utility model provides a kind of high-performance, paper web static eraser simple to operation.This static eraser can be eliminated static on the paper web, removes the paper powder, and can be according to the production requirement lifting.
The purpose of this utility model is achieved through the following technical solutions:
A kind of paper web static eraser is characterized in that: it comprises hairbrush, clamping plate, static derivation line and lowering or hoisting gear, and described hairbrush is arranged in the clamping plate and by clamping plate and fixes; Clamping plate are installed on the lowering or hoisting gear, and hairbrush rises or descends with lowering or hoisting gear and contacts or leave paper; Static derivation line is arranged on the clamping plate and by soleplate and communicates with ground.Static is derived line can all be directed to big ground with the static on the paper web.
For guaranteeing to remove the effect of static on the paper web, described hairbrush is made by conductive material in the utility model.The width of hairbrush should be suitable with paper web.The quantity of hairbrush can be one group of plurality of rows, sets as required.
In process of production, contact or leave paper for ease of hairbrush, hairbrush is arranged on the lowering or hoisting gear, described lowering or hoisting gear comprises lifting body, slide rail, turbine, scroll bar and motor, clamping plate are installed on the lifting body, lifting body can move along slide rail under turbine and scroll bar effect, and turbine and scroll bar are by drive of motor.The movement travel of lowering or hoisting gear can be determined by limit switch, arrives the optimum position to guarantee lifting body hairbrush when rising, and lifting body is not run into ground when descending.For guaranteeing that the hairbrush two ends can steadily contact with paper web simultaneously, synchronization lifting is answered at the two ends of lifting body, can guarantee the synchronization lifting at lifting body two ends by synchronizing shaft.
The utility model utilizes hairbrush to be used as static eraser for solving the electrostatic problem in the paper manufacture process, and the hairbrush full width contacts operating paper, can not only eliminate static, can also remove the paper powder, reduces the paper defects that back segment forms.Simultaneously hairbrush can free lifting, when ordinary production, can lower as required and carry out brush cleaning.Compared with prior art, the utility model can be eliminated static on the paper web, avoids paper web to enter that absorption paper powder and paper scrap enter nip behind the calender, has stopped the generation of paper defects, has guaranteed the quality of product.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Five, the specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of paper web static eraser described in the utility model comprises hairbrush 1, clamping plate 2, static derivation line 3 and the lowering or hoisting gear 4 made by conductive material.Hairbrush 1 is arranged in the clamping plate 2 and by clamping plate 2 and fixes.Clamping plate 2 are installed on the lowering or hoisting gear 4, and hairbrush 1 rises or descends with lowering or hoisting gear 4 and contacts or leave paper 6, and paper 6 is installed on the winding roll 7.Lowering or hoisting gear 4 comprises lifting body 41, slide rail 42, turbine 43, scroll bar 44 and motor 45, and clamping plate 2 are installed on the lifting body 41, and lifting body 41 can move along slide rail 42 under turbine 43 and scroll bar 44 effects, and turbine 43 and scroll bar 44 are by motor 45 transmissions.Static derivation line 3 is arranged on the clamping plate 2 and by soleplate 5 and communicates with ground.The quantity of hairbrush 1 adopts one group of two row, and its width and paper web are suitable.
When needs are eliminated static, starter motor 45, turbine 43, scroll bar 44 promote lifting body 41, determine that by the mechanical position limitation at scroll bar 44 tops hairbrush 1 final full width touches paper 6, make on the paper 6 with static derive line 3 and the soleplate 5 last the earth that arrive via hairbrush 1, static, realize static eliminating function.
After the long period use, the brush of hairbrush 1 can gather the paper powder, needs regularly cleaning; But starter motor 45, turbine 43, scroll bar 44 descend lifting body 41, reduce to spacing minimum point by the limit switch decision lifting body 41 of slide rail 42 bottoms.Brush head can clean with dust catcher and comb.
