Abstract
The invention relates to a mechanical device, in particular to an automatic bed sheet replacement device which is composed of a shaft end spring (1), an axially-movable compression roller (2), an axially-fixed compression roller (3), a material storage roller (4), bed sheets (5), a traction roller (6), an electromagnet (7), a limiting rod (8), a push rod (9), a swing rod (10), a friction wheel (11), a resetting spring (12), a limiting rod (13) and a bed frame (14). The electromagnet excites the swing rod to drive the traction roller to pull the bed sheets to realize quantitative feeding motion of the bed sheets; clean bed sheet cloth is wound on a material storage roller (1) of an adjustable tensioning mechanism, the bed sheets are connected to form a roll, the material storage roller (1) is fixed to a rack, and the cloth roll where the clean bed sheets (5) are mounted, the axially-movable compression roller (2) and an axially-fixed compression roller (3) are arranged parallelly. The electromagnet drives the friction wheel which drives the traction roller, the traction roller pulls the bed sheets to move by set length (equal to width of a bed), and people utilize different bed sheet sections each time, so that automatic bed sheet replacement is realized.
Description
Technical field
The present invention relates to a kind of machinery, particularly relate to a kind of device that automatically more changes the sheet.
Background technology
Along with people's living standard improves, people more and more note safe and sanitary in public places, in hospital or hotel, sheet will be changed in time, otherwise easily cause various pathophoresis, unhygienic dangerous, so just invent a kind of sheet apparatus for automatic change, save manpower replacing construction, make life more convenient.
Summary of the invention
The object of the present invention is to provide a kind of device that automatically more changes the sheet, this device is by solenoid actuated friction pulley, and friction pulley drives traction rod, and carry-over pinch rolls pull sheet to move preseting length (width of bed), everyone utilizes different sheet section at every turn, thus realizes automatically more changing the sheet.
A kind of device that automatically more changes the sheet, described device, by axle head spring, is axially moveable pressure roller, axial restraint pressure roller, material stock roller, sheet, carry-over pinch rolls, electric magnet, gag lever post, push rod, fork, friction pulley, back-moving spring, gag lever post, and bedstead forms; Electric magnet excitation fork, drives carry-over pinch rolls, pulls sheet band, realize the quantitative feed motion of sheet; Adjustable tension mechanism storing roller is wound around clean sheeting, several sheets connect together formation one volume, storing roller is fixed on frame, clean sheet yardage roll is installed, is axially moveable pressure roller, axial restraint pressure roller is arranged in parallel, be axially moveable pressure roller end and axle head spring is housed, two rollers are tapered roll, are axially moveable to produce normal pressure between pressure roller and axial restraint pressure roller and tighten material stock roller; Apron quantitive conveyor structure is pulled by carry-over pinch rolls, and carry-over pinch rolls are fixed on friction pulley, and fork drags push rod, and push rod promotes friction pulley by the groove of friction pulley and rotates, and back-moving spring provides reset for sheet continuous feed.
Described one more changes the sheet device automatically, described frictional drive, and fork both sides are provided with two gag lever posts, restriction traction amplitude.
Described one more changes the sheet device automatically, and described fork is by solenoid actuated.
The object of the invention is to be achieved through the following technical solutions:
Advantage of the present invention and effect are:
1. the present invention is by solenoid actuated friction pulley, friction pulley drives traction rod, carry-over pinch rolls pull sheet to move preseting length (width of bed), everyone utilizes different sheet section at every turn, thus realize automatically more changing the sheet, avoid because of bed sheet replacing not in time, occur that disease antibacterial is by using the cross infection of public sheet.Mechanism is compact, with low cost, and reliable operation is easy to operate.
2. the quantitative traction apparatus design of the present invention, if sheet amount of movement controls bad, not that new sheet section does not cover position, it is exactly excessive movement, cause waste, the design's sheet moves and is pulled by carry-over pinch rolls, carry-over pinch rolls are fixed on friction pulley, fork drags push rod, push rod promotes friction pulley by the groove of friction pulley and rotates, this frictional drive, prevent friction pulley and carry-over pinch rolls reversing, fork both sides are provided with two gag lever posts, restriction traction amplitude, namely the object accurately controlling sheet amount of movement is reached, fork is finally by solenoid actuated, back-moving spring plays reset role, for sheet continuous feed provides reset capability.
3. tension mechanism design of the present invention, in use relax to prevent sheet, the design adopts and is axially moveable pressure roller, axial restraint pressure roller, two rollers are cone roller, and the axle head being axially moveable pressure roller is provided with Compress Spring, normal pressure can be produced between two rollers, tighten material stock roller, then realize controlling frictional force effect, thus realize the effect of tightening sheet in the reasonable scope.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram;
Fig. 2 is pusher structure schematic diagram.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in detail.
In figure, parts are: by axle head spring 1, are axially moveable pressure roller 2, axial restraint pressure roller 3, material stock roller 4, sheet 5, carry-over pinch rolls 6, electric magnet 7, gag lever post 8, push rod 9, fork 10, friction pulley 11, back-moving spring 12, gag lever post 13, and bedstead 14 forms.Storing roller 1 is wound around clean sheeting (several sheets connect together formation one volume), storing roller 1 is fixed on frame, clean sheet 5 yardage roll is installed, is axially moveable pressure roller 2, axial restraint pressure roller 3, be arranged in parallel, be axially moveable pressure roller 2 end axle head spring 1, two roller is housed is tapered roll, be therefore axially moveable between pressure roller 2 and axial restraint pressure roller 3 and produce normal pressure, material stock roller 4 can be tightened, prevent sheet from relaxing.The design's sheet moves and is pulled by carry-over pinch rolls 6, carry-over pinch rolls 6 are fixed on friction pulley 11, and fork 10 drags push rod 9, and push rod 9 promotes friction pulley 11 by the groove of friction pulley and rotates, this frictional drive, prevent friction pulley and carry-over pinch rolls reversing, fork both sides are provided with two gag lever posts 8 and 13, restriction traction amplitude, namely the object controlling sheet amount of movement is reached, fork 10 is finally driven by electric magnet 7, and back-moving spring 12 plays reset role, for sheet continuous feed provides reset capability.Said apparatus can realize laying sheet function without the reliable and stable conveying of bounce-back.Be stored on carry-over pinch rolls by the sheet section crossed, after all sheets are all finished in the direction of the width, take out and renew sheet volume.The use of whole device can avoid disease antibacterial by using the cross infection of public sheet, and can convenient and swiftly at any time more change the sheet, and saves manpower, is particularly useful for the public place such as hospital and hotel.
