Abstract
The utility model discloses a roll paper center rotary shaft. The roll paper center rotary shaft comprises two supporting rods, a center coiling block, two movable check rings and two rolling bearings, wherein the two supporting rods are arranged at the two ends of the center coiling block respectively; locating grooves are formed in the two ends of the center coiling block; the two movable check rings are symmetrically arranged on the locating grooves in a sleeved mode; the two rolling bearings are arranged on the two supporting rods in a sleeved mode. By means of the mode, according to the roll paper center rotary shaft, as the rolling bearings and the movable check rings are arranged, no friction exists between the roll paper center rotary shaft and a feeding and discharging frame when the roll paper center rotary shaft rotates, durability is good, the movable check rings can effectively prevent roll paper from sliding right and left under the blocking of fixing bolts, and running stability is good.
Description
Technical field
The utility model relates to production line of toilet napkin transmission field, particularly relates to a kind of coil paper central rotating shaft.
Background technology
Sanitary napkin is dealt with the protective articles of menstruation as a kind of women of help, differentiation and the development of various ways are passed through, and modern sanitary napkin is a kind of material of tool absorption power, high molecular polymer and high molecular polymer extrusion coating paper that main material forms for cotton, adhesive-bonded fabric, paper pulp or above material compound, principal feature is that water absorbing capacity is large, disposable use, clean hygiene.
General mature women can use sanitary napkin every month, and intermenstrual period will change several piece every day, so the market demand of sanitary napkin is very large, impels the manufacturing enterprise of sanitary napkin constantly to carry out industrial upgrading, improves output and quality, caters to customer.In the production of sanitary napkin, need coil paper raw material to unreel, because the volume of coil paper raw material is larger, need to insert a central rotating shaft in coil paper central hole, then prize to broadcast on frame and unreel, what central rotating shaft and broadcasting adopted between frame is simple friction of rolling, smoothness of operation is poor, and because the diameter of coil paper centre hole is generally greater than central rotating shaft diameter, so coil paper easily horizontally slips in the process unreeling.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of coil paper central rotating shaft, and when rotation, with to broadcast frame friction little, coil paper run stability is high, can prevent that coil paper from sliding.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of coil paper central rotating shaft is provided, comprise: two strut bars, center reel, two movable back-up rings and two antifriction-bearing boxs, described two strut bars are separately positioned on the two ends of center reel, the two ends of described center reel are provided with positioning groove, described two movable back-up ring symmetries are enclosed within on positioning groove position, and described two antifriction-bearing boxs are enclosed within respectively on two strut bars.
In preferred embodiment of the utility model, described two strut bars and center reel concentric arrange.
In preferred embodiment of the utility model, between described strut bar and center reel, adopt welding manner to be connected.
In preferred embodiment of the utility model, on described positioning groove, be provided with bolt of rear end plate.
In preferred embodiment of the utility model, described two antifriction-bearing boxs are symmetricly set on the two ends of center reel.
The beneficial effects of the utility model are: a kind of coil paper central rotating shaft that the utility model is pointed out, be provided with antifriction-bearing box and movable back-up ring, when rotation with broadcast frame and there is no friction of rolling, durability is good, movable back-up ring can effectively avoid coil paper to horizontally slip under the stopping of bolt of rear end plate, and smoothness of operation is good.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of a kind of coil paper central rotating shaft one preferred embodiment of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, two strut bars, 2, center reel, 3, movable back-up ring, 4, bolt of rear end plate, 5, antifriction-bearing box.
The specific embodiment
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of coil paper central rotating shaft, comprise: two strut bars 1, center reel 2, two movable back-up rings 3 and two antifriction-bearing boxs 5, described two strut bars 1 are separately positioned on the two ends of center reel 2, the two ends of described center reel 2 are provided with positioning groove, described two movable back-up ring 3 symmetries are enclosed within on positioning groove position, and described two antifriction-bearing boxs 5 are enclosed within respectively on two strut bars 1.
A kind of coil paper central rotating shaft of the utility model symmetry is good, and described two strut bars 1 and the 2 concentric settings of center reel, roll steadily.
Further, between described strut bar 1 and center reel 2, adopt welding manner to be connected, firmly degree is high, can tackle the weight of coil paper raw material.
Further, on described positioning groove, be provided with bolt of rear end plate 4, spacing by bolt of rear end plate 4 adjusting activity back-up rings, thus prevent that coil paper from horizontally slipping unreeling in process.
Further, described two antifriction-bearing boxs 5 are symmetricly set on the two ends of center reel 2, and while unreeling, antifriction-bearing box 5 has been avoided strut bar and the friction of rolling of broadcasting frame, and durability is good.
In sum, a kind of coil paper central rotating shaft that the utility model is pointed out, compared with common central rotating shaft, can prevent that coil paper from horizontally slipping unreeling in process, and degree of stability is high, and is rotated by antifriction-bearing box while unreeling, rubs little, and durability is good.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
