The roller comprises roll paper 01, a roller 1, an anti-slip sleeve 2, an elastic bulge 3, a gear 4, an outer shell 5, a limiting disc 6, an elastic buckle 7, a limiting groove 8, a winding drum assembly 9, an elastic piece 10 and a roller box 11.

Detailed Description

The present invention will be further explained with reference to the following embodiments and accompanying drawings.

In the embodiment, as shown in FIGS. 1 to 7: the utility model provides a twin drum goes out paper device, includes in pairs, leans on two cylinders 1 of tight setting, two clearance between the cylinder 1 is used for the centre gripping and draws forth stock form 01, the sliding sleeve 2 is prevented in the outside of cylinder 1. The two rollers 1 of this embodiment keep the centre gripping to the stock form 01, and antiskid cover 2 adopts materials that have elasticity and higher coefficient of friction such as rubber sleeve, guarantees both to keep the tight fit state but be unlikely to the card dead between stock form 01 and roller 1, roller 1 and the roller 1, and when external force draws the stock form, roller 1 can rotate, and roller 1 can stop the rotation at once again when external force disappears, just so can effectively avoid drawing the condition of drawing too much toilet paper, thereby reduce extravagantly, guarantee the health.

In the embodiment, as shown in fig. 3 and 4: the periphery wall of the anti-skid sleeve 2 is provided with a plurality of elastic bulges 3. This structure can guarantee that stock form 01 and cylinder 1 can the even contact along axial direction, avoids appearing the tight one end condition loose of one end between two cylinders 1 because of the error of cylinder 1 appearance and axle center, guarantees to go out paper smoothly.

In the example, as shown in fig. 3: the end parts of the two rollers 1 are provided with gears 4 which are meshed with each other and rotate in the same speed and opposite directions. This structure can guarantee that two cylinders 1 are rotatory at the constant speed, avoids stock form 01 one side fast one side slow and the fold appears.

In the embodiment, as shown in fig. 1, 5 and 6: still including shell body 5, cylinder 1 is installed in shell body 5, cylinder 1 with be equipped with unidirectional rotation stop device between shell body 5. Specifically, the one-way rotation stop device is including setting up 1 tip of cylinder spacing dish 6 and setting are in elasticity on the shell body 5 is detained 7, spacing dish 6 is gone up and is had a plurality of spacing grooves 8 along the circumference equipartition, be equipped with in the spacing groove 8 with the consistent one-way groove of 6 direction of rotation of spacing dish. This embodiment structure can further guarantee that cylinder 1 can stop rotating at once when external force disappears, can also produce the pause and frustrate sense when dragging stock form 01, makes the length of control play paper that the user can be better.

In the examples, as shown in fig. 1: and a winding drum assembly 9 for placing the roll paper 01 is also arranged on the outer shell 5. The roll assembly 9 of this embodiment is composed of an inner shaft and an outer cylinder which are concentrically arranged, and an inner core of the roll paper 01 is fitted over the outer cylinder so as to be rotatable around the inner shaft.

In another embodiment, as shown in FIG. 7: the distance between the two rollers 1 is adjustable and is pressed by an elastic element 10. Still including shell body 5, two cylinder 1 is furnished with independent cylinder box 11, at least one cylinder box 11 can the slidable install in the shell body 5, elastic component 10 is the extension spring, and both ends are fixed respectively two on the cylinder box 11. According to the structure of the embodiment, the elastic members 10 with different stiffness coefficients can be replaced according to the characteristics of the roll paper 01, so that smooth paper discharge is ensured.

It is obvious that the above embodiments of the present invention are only examples for illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. There is no need or no way to give poor examples of all embodiments.
