Description

A kind of expansion type body paper chuck

Technical field

The utility model relates to body paper chuck technical field, and specifically, it relates to a kind of expansion type body paper chuck.

Background technology

Tradition body paper chuck is a pyramid, and it makes core tube unbalance stress when clamping former refill tube, and in use the drawback that can burst body paper paper tube and inner edge paper causes tail paper to use difficulty, and tail paper condemnation factor surpasses more than 2 ‰.CN2595780Y discloses the patent that a kind of name is called expansion type body paper chuck, it is provided with mandrel, running-fit has orienting sleeve on the mandrel, axial retracing spring is housed between orienting sleeve inner chamber front end and the mandrel, the orienting sleeve sidewall is provided with the radially-directed hole that is no less than three in a circumferential direction, be embedded with slide block in the radially-directed hole movingly, the slide block inner end surface is facing to the inclined-plane that turns forward that vertically is provided with on the mandrel sidewall.This expansion type body paper chuck can actv. solves the problem of core tube unbalance stress, but its spacing be by on parts among orienting sleeve and the mandrel, limit sliding chutes longitudinally being set, the pin that is provided with on another parts embeds in the limit sliding chutes movingly.This spacing design not only complex structure but also pin in case damage to change and be difficult for.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of spacing body paper of expansion type easily chuck to be provided.

A kind of expansion type body paper chuck, comprise mandrel, be with orienting sleeve on the mandrel movingly, orienting sleeve is provided with the pilot hole that runs through jacket wall, be embedded with slide block in the pilot hole movingly, the inner end surface of slide block is facing to the mandrel groove that axially is provided with on the mandrel outer wall, and described mandrel groove tilts to the mandrel top, and described mandrel is provided with the body that runs through the mandrel bottom; Top of chamber is provided with nut in the described orienting sleeve.

As preferably, described inboard wall of tube body is provided with back-up ring; Described nut is connected with the screw by body; Between described orienting sleeve inner chamber front end face and the mandrel bottom axial retracing spring is housed; The mandrel space that described retracing spring one end and mandrel and body form is inconsistent, and the other end and orienting sleeve inner chamber front end face are inconsistent.

As preferably, the passage between the described back-up ring is identical with the nail body diameter of screw.

As preferably, described slide block outer face is circular-arc.

Practical beneficial effect of the present utility model is:

1, screw of the present utility model is connected with nut by body, and the passage between the back-up ring is identical with the nail body diameter of screw, and the bottom of screw may be stuck on the back-up ring, its spacing convenience, and it is convenient to change;

2, the utility model need not power-assisted, wears paper success rear slider and tightens up along with the body paper frame is traversing or loosen to expand automatically in paper web and launch and shrink, and the slide block outer face is circular-arc, and actv. solves the problem of core tube unbalance stress more, improves the body paper degree of utilization;

3, retracing spring one end and mandrel space are inconsistent, and the other end and orienting sleeve inner chamber front end face are inconsistent, make retracing spring stressed evenly, have increased practicality of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

A kind of expansion type body paper chuck, comprise mandrel shown in Figure 21, be with orienting sleeve shown in Figure 12 on the mandrel 1 movingly, orienting sleeve 2 is provided with the pilot hole 21 that runs through jacket wall, be embedded with slide block 4 as shown in Figure 3 in the pilot hole 21 movingly, slide block 4 outer faces are circular-arc, and the inner end surface of slide block 4 is facing to the mandrel groove 11 that axially is provided with on mandrel 1 outer wall; As shown in Figure 2, mandrel groove 11 tilts to mandrel 1 top; As shown in Figure 4, mandrel 1 is provided with the body 12 that runs through mandrel 1 bottom, and body 12 inwalls are provided with back-up ring 121; Top of chamber is provided with nut 22 in the orienting sleeve 2; Described nut 22 is connected with the screw 3 by body 12; Between orienting sleeve 2 inner chamber front end faces and mandrel 1 bottom axial retracing spring 5 is housed; The mandrel space 13 that retracing spring 5 one ends and mandrel 1 and body 12 form is inconsistent, and the other end and orienting sleeve 2 inner chamber front end faces are inconsistent.Passage 122 between the back-up ring 121 is identical with the nail body diameter of screw 3.As shown in Figure 5, assembling back orienting sleeve 2 running-fits is enclosed within on the mandrel 1.

Through experiment, every loom utilizes the minimum waste that reduces by 40 kilograms of tail paper every day of expansion type body paper chuck, with the minimum 2500 yuan of calculating of paper per ton, can save 100 yuan every day, can save 30,000 6 thousand yuan every year.As seen its economic benefit is obvious.

The above only is a preferred embodiment of the present utility model; be not so promptly limit protection domain of the present utility model; the equivalent structure transformation that every utilization the utility model specification sheets and accompanying drawing content are done; directly or indirectly be used in other relevant technical fields, all in like manner be included in the claim of the present utility model.
