Description

Dial paper bowl

Technical field

The utility model belongs to paper making equipment technical field, and in particular to dials paper bowl.

Background technology

In the paper production of paper-making industry, roll paper is last one of technique on assembly line, and winding roll effect is will to flow Paper roll on waterline is on winding roll, after winding roll is rolled up paper, needs to re-replace a winding roll (empty roller), has certain The winding roll of initial velocity moves closer to the cooling cylinder with certain rotating speed, when winding roll and cooling cylinder are tangent, by cooling cylinder as driving wheel Winding roll rotation is driven, the winding roll (follower) of rotation, which is started to work, completes the action of roll paper.With the development of paper-making industry, paper Speed constantly increases, and the door amplitude variation of paper is wide, and paper roll quality is very big, and after tangent, friction slip can be generated between cooling cylinder and winding roll Phenomenon generates the defects of revolutional slip causes disconnected paper, wadding.So in high speed papermaking production process, by the use of cooling cylinder as driving wheel Winding roll rotation is driven to have been unable to meet the requirement of production.Therefore, a kind of novel group of paper bowl how is researched and developed, changes traditional structure Form, not only with urgent researching value, it may have good economic benefit and commercial application potentiality.

Embodiment 1

As shown in Figure 1, dialling paper bowl, including drive roll 11 and help roll 5, the drive roll 11 and help roll 5 are by turning Axis 2 is connected with motor, and the outer wall of drive roll 11 is arranged with blanket roller, and the outer wall of blanket roller, which outwardly protrudes to be extended, smooth pad Piece 7 and coarse gasket 9, smooth gasket 7 and coarse gasket 9 are staggered along the circumferential direction cycle of blanket roller, smooth gasket 7 and thick Card slot 8 is provided between rough gasket 9；The help roll 5 is arranged on the rear of drive roll 11, and is in interlock up and down with drive roll 11 Formula is arranged, and the both ends of help roll 5 set up connecting rod 4, and the end of connecting rod 4 and shaft 2 connect, and the both ends of shaft 2 are slidingly connected A pair of of idler wheel 3.

Paper 1 between drive roll 11 and help roll 5 tilts upward, and 20 ° -40 ° are set as with the angle of horizontal plane.Make paper 1 along between drive roll 11 and help roll 5 to driving front when, keep certain tension, make paper 1 steadily move forward.

The middle part of help roll 5, which circumferentially outwardly protrudes to be extended, annular ridge 6, and the thickness of annular ridge 6 is 2- 5mm, the width of annular ridge 6 are more than its thickness.6 slightly protruding of annular ridge makes help roll 5 and paper 1 in the surface of help roll 5 When contacting with each other, 6 preferential contact paper 1 of annular ridge, and closely engage between paper 1, especially between the central axes of paper Larger tension is formed, ensure that annular ridge 6 is fastened on the axis line position of paper 1, the central axes of annular ridge 6 and paper always Running orbit is consistent.The annular ridge 6 plays paper certain position-limiting action, reduces paper 1 and position occurs during transmission Move phenomenon.

A pair of of idler wheel 3 is fastened on the both sides line position of paper always, and idler wheel 3 and the rear end of paper contact with each other, and play auxiliary The effect of pressing when paper 1 is to driving front, closely engages between idler wheel 3 and the both sides of paper, i.e., between two side lines of paper Larger tension is formed, ensure that idler wheel 3 is consistent with two side line running orbits of paper.

Damping roller 10 is set as blanket roller or rubber rollers, and the diameter of damping roller 10 is consistent with the diameter of help roll 5.

When damping roller 10 is using blanket roller, due to the particularity of own material, certain cushion effect is made it have, it is ensured that There are stronger clamping power between inside drive roll 11, while meet the requirement of the certain toughness of paper.

Inside and outside for iron material matter when damping roller 10 is using rubber rollers, centre is rubber material, good damping effect, during use Time is long, and certain draw is played to paper.

Carrying out practically process is：Paper 1 between help roll 5 and drive roll 11 is passed through, and be wrapped on drive roll 11, is led to Cross motor driving drive roll 11 rotate, drive roll 11 rotation drive paper 1 drive forwards, paper 1 in transmission process with drive roll 11 The smooth gasket 7 and coarse gasket 9 on surface contact with each other, and it is arc-shaped that smooth gasket 7 and coarse gasket 9 are disposed as cross section Tile like structure, curvature are consistent with 10 curvature of damping roller.The surface of smooth gasket 7 is hydraulically smooth surface, the surface of coarse gasket 9 Anti- sliding rib is provided with, axial equidistantly arrangement of the adjacent anti-sliding rib along damping roller 10, smooth gasket 7 and being bonded for paper 1 are close Property is strong, small with the frictional force of paper when chart speed is excessively high, plays the role of bracketing to paper；When chart speed is too low, coarse pad Piece 9 increases the frictional force between paper, more apparent to the driving force of paper, paper can be driven quickly to move ahead；The depth of card slot 8 Degree is consistent with the thickness setting of smooth gasket 7, coarse gasket 9.Card slot 8 plays certain transitional function, when paper is along actively When roller 11 is to driving front, certain tensile force is generated to paper, gap is formed between card slot 8 and paper, paper is avoided to fit to On drive roll 11, to complete the work of the roll paper of high-speed cruising paper, chart speed is high or low in no matter producing in this way, can ensure roll paper The quality of the normal roll paper of roller and roll paper, it is easy to use and production efficiency can be improved.It is secondary fixed that help roll 5 below forms paper Position effect, while ensure the tensile force of paper, improve the stationarity of paper onwards transmission.

The above is not the limitation to the utility model, it should be pointed out that：For the ordinary skill people of the art For member, under the premise of the utility model in essence range is not departed from, several variations, modifications, additions or substitutions can also be made, These improvements and modifications also should be regarded as the scope of protection of the utility model.
