Abstract

The utility model relates to the improvement on a device of coiling continuous long width sheet materials. The improvement is characterized in that at least a rotating floating carrier roller is arranged below a winding-up roller. The utility model is used for winding sheet material with the large width and/ or thick sheet materials, so as to not only prevent the winding-up roller from drooping, but also ensure the coiling has uniform tightness, and the winding is tidy and smooth. The floating carrier roller separates with the winding-up roller at the beginning period of the winding, so as to be convenient to the coiling at the beginning period of the winding. The constant pressure floating of the floating carrier roller not only keeps the carrying of the winding roller, but also keeps the constant pressure to the winding-up roller and avoids stuck phenomenon along with the increase of the winding.

Description

Continuous length and width degree sheet material wrap-up

Technical field

Utility model belongs to a kind of continuous length and width degree sheet material wrap-up, relates in particular to a kind of wrap-up of can the big fabric width sheet material of rolling and having permanent tension rolling function.

Background technology

Existing continuous slice wrap-up during for example plastic sheeting or plastics geotextile are produced adopts the coiling motor to connect usually and drives the rolling of rolling cylinder coiling, and for example torque motor direct drive take up roll is realized the coiling rolling to continuous slice.This kind wrap-up is for big width, width 〉=6.0 meter for example, and/or the heavy gauge above geomembrane of thickness 〉=0.5mm for example, because of the film weight per unit area is big, objectively there is the rigidity deficiency in long wind-up roll, adds that rolling weight increases considerably, very easily cause wind-up roll sagging, and cause rolling film degree of tightness inhomogeneous, and cause rolling irregular, be difficult to realize normal rolling.If strengthen the wind-up roll diameter, though can improve stiffness, can make the mechanical equipment heaviness, the rolling amount reduces, and the operating cost increase, and major diameter wind-up roll processing and fabricating is also difficult simultaneously.Though people propose multiple improvement to the continuous sheet wrap-up, for example: the disclosed geomembrane blowing of Chinese patent CN2559621 mechanical membrane wrap-up, rolling parts are provided with roller (4), (5) of horizontal parallel setting and place the center winding device (6) of top between roller (4), (5).This wrap-up complex structure, and can not solve the take up roll sagging problem.Chinese patent CN2102911, CN2804023, CN101100256 etc. all relate to the rolling constant-tension to the improvement of wrap-up, do not have equally to solve the take up roll sagging problem.Therefore still having is worth improved place.

The utility model content

The utility model purpose is to overcome above-mentioned prior art deficiency, provides a kind of simple in structure, and operating cost is low, can prevent effectively that wind-up roll is sagging, and the neat continuous length and width degree sheet material wrap-up of reeling.

The utility model purpose realizes that main the improvement is the unsteady carrying roller that at least one rotation is set below former wind-up roll, by the rest to wind-up roll, reach and reduce the sagging of wind-up roll; Secondly, the rotation of carrying roller also can be assisted to roll and be pushed away wind-up roll and help rolling, and compacting ring is around sheet material, makes that to furl sheet material neat.Specifically, the continuous length and width degree of utility model sheet material wrap-up comprises that torque motor drives take up roll, it is characterized in that the take up roll below has the unsteady carrying roller of a rotation at least.

Wherein a kind ofly better be, the unsteady carrying roller of rotation has two, is relatively arranged on the take up roll down either side, and 2 supports and take up roll are three dot structures, good stability, unsteady carrying roller that can more single rotation, more balance and stability.

Carrying roller floats, and mainly is to make it along with coiling thickness increases, and keeps the rest of take up roll and compresses, and can be the pressure spring device to be set supporting on the carrying roller, by the bounce of spring, makes carrying roller be close to pressure effect take up roll all the time; Wherein a kind of being preferably adopted constant voltage air cylinder device (cylinder+constant voltage source of the gas), and it is changed with the volume of reeling, and remains the constant relatively rest pressure of take up roll, can prevent effectively that the increase of carrying roller pressure from causing take up roll stuck.Said float a kind ofly is more preferably the coiling initial stage, makes carrying roller to the separated attitude of take up roll, and promptly carrying roller starting point (vertex) does not contact with take up roll, rolls up on the initial stage sheet material that helps reeling.Carrying roller rotates, and helps to help rolling, simultaneously take up roll is also had auxiliary impetus.

The continuous length and width degree of utility model sheet material wrap-up, because particularly side-lower increases the unsteady carrying roller of at least one rotation below take up roll, be used for big width and/or thick sheet and reel, prevented effectively that not only take up roll is sagging, and can guarantee that the rolling degree of tightness is even, it is neat, smooth to reel.The carrying roller that floats is reeled the initial stage, to the separated attitude of take up roll, helps last volume of coiling initial stage.The constant pressure of unsteady carrying roller is floated, and not only can keep the take up roll rest, and increase along with reeling, and can remain the constant pressure to take up roll, prevents stuck.

Below in conjunction with a specific embodiment, utility model is further understood in exemplary illustration and help, but the embodiment detail only is for utility model is described, do not represent utility model design whole technical schemes down, therefore should not be construed as the technical scheme qualification total to utility model, some do not depart from the unsubstantiality of utility model design and change at technical personnel, for example simple change of technical characterictic or replacement to have same or similar technique effect, the novel scope of protecting of all true usefulness.

The specific embodiment

Embodiment: referring to accompanying drawing, the continuous length and width degree of utility model sheet material wrap-up, comprise wind-up roll 4 and drive rolling torque motor 6, the wind-up roll down either side respectively has a liftable to float, the carrying roller 1 isometric (two carrying rollers are the setting of " people " font) with take up roll, respectively having motor 2 to drive rotates, two ends by supporting shaft holder at guide rail 3 rail levels, do unsteady (floating downward by cylinder 5 drives with coiling expansion, unloading the volume back rises), the carrying roller 1 initial vertex that wherein floats does not contact with take up roll, after roller coiling to be spooled was a certain amount of, a carrying roller began stressed support, and cylinder 5 has gas bag 7 air feed and keeps cylinder to be constant pressure (constituting the constant voltage air cylinder device) all the time.

To those skilled in the art; under utility model design enlightenment; some distortion that can directly derive or associate from this patent disclosure; or the substituting of known technology commonly used in the prior art; and the mutual various combination between feature; for example adopt the spring floating rest; adopt different motor-driven to reel and a carrying roller; and adopt other that carrying roller is kept take up roll constant pressure arrangement or the like; can both realize and basic identical function of the foregoing description and effect; no longer describe in detail for example one by one, all belong to this patent protection domain.
