[technical field]
The utility model relates to a kind of winding mechanism, particularly relates to a kind of cutting machine air sac slippage batch up gear.
[background technology]
At present, in industries such as papermaking, plastics, printing, the winding off spindle that is used to prop up bobbin is a kind of very important parts that batch.When material is involved in capable cutting and rewinding, will expect usually to roll up to be enclosed within on the winding off spindle to reel.Along with the continuous increase of material volume, just need control its tension force, if Tension Control is not accurate enough, furling of material volume is just not steady.The speed of wrap inequality that this can cause banded material causes the phenomenon that had pine and tension in the same ribbon material, and occurs the overlapping problem of multilayer easily, thereby seriously influences the inherent quality of product.
Mentioned a kind of inflatable axle in the Chinese patent 200320110958.3, constitute by air bag component, expand block assembly, hollow axis body assembly etc., bloated block assembly comprises bloated piece, spring leaf, interior bloated plate, bloated piece is the strip derby, adopt screw to be contained on the interior plate that expands, can be used for batch up gear as industrial banded material.Its shortcoming is that the piece that expands is fixed with the area of contact of interior bloated plate, and the tension force size is difficult for regulating, and in addition, removes when expanding block assembly and also comparatively bothers.
[utility model content]
For addressing the above problem, the utility model provides a kind of cutting machine air sac slippage batch up gear, the technical solution of the utility model directly combines air bag with rewinding collar inwall, and be easy to adjust its conjugation, thereby the coiling that makes material is easy fracture or sideslip not, can after-combustion major diameter and the narrower material volume of width.
The technical scheme that the utility model is taked is:
Cutting machine air sac slippage batch up gear, comprise: a winding off spindle, it is outside equipped with the rewinding collar, be provided with a gas piping that is connected with a pneumatic supply in this winding off spindle, be arranged at intervals with the air flue that array radially runs through this winding off spindle axial wall and is connected with this gas piping on this winding off spindle, this winding off spindle axial wall at these places, air flue outer end is provided with the strip groove; Some air bags are divided in the groove of this winding off spindle, and each air bag closely links to each other with a described air flue, and these air bags are clogged this groove and ejection outside groove after inflating.
The radial symmetry of arranging of every group of air flue on the described winding off spindle, and the air flue number is an even number.
The number of every group of described air flue is 4 or 6.
The end face of described air bag is provided with a friction lining.
The described rewinding collar is unidirectional torsion ring, and it can only rotate towards single direction.
The beneficial effects of the utility model are: structure design of the present utility model contacts with inflatable air bag by making the rewinding collar, the transmission effect is more direct, size by control break pneumatic supply pressure, promptly can effectively regulate the combination degree between the air bag and the rewinding collar, simple in structure, be convenient to operation.Solved in the prior art problem that when the material volume is increasing batch up gear is difficult for adjustment of tonicity.

[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Figure 1 and Figure 2, Fig. 1 is a simplified diagram of the present utility model, and Fig. 2 is part sectional view of the present utility model.Cutting machine air sac slippage batch up gear comprises: a winding off spindle 10, and it is outside equipped with the rewinding collar 20, and the rewinding collar 20 is unidirectional torsion ring, and it can only rotate towards single direction.According to actual needs, this rewinding collar 20 can be one, also can be evenly be provided with at interval a plurality of.Be provided with a gas piping 30 that is connected with a pneumatic supply (not shown) in the winding off spindle 10, be arranged at intervals with array on the winding off spindle 10 and radially run through the axial wall 11 of this winding off spindle 10 and the air flue 12 that is connected with this gas piping 30, these winding off spindle 10 axial walls 11 of these air flue 12 outer ends are provided with groove 13; Some air bags 40, air bag 40 is a strip shape hollow capsule bag, is divided in the groove 13 of this winding off spindle 10, and each air bag 40 links to each other with an air flue 12, and when pneumatic supply during to gas piping 30 ventilation, gas charges in the air bag 40 by each air flue 12.
Please in the lump with reference to Fig. 2 (a), Fig. 2 (b) and shown in Figure 3, the radial symmetry of arranging of every group of air flue 12 on the winding off spindle 10, and the air flue number is even number and is evenly distributed on the circumference of winding off spindle 10k.As preferred implementation, the air flue number of described every group of air flue 12 is 4 or 6.The purpose of She Zhiing is stressed evenly in order to guarantee winding off spindle material volume in-to-in in the process of reeling like this, avoids outer fracture of material curly hair business or sideslip.In some cases, even can be by closing certain several air flue wherein, and the airway unobstructed that keeps other is regulated the friction force of winding off spindle for the rewinding collar, for example, when the air flue number is 4, close 2 adjacent mutually air flues, then remaining 2 air flues still can guarantee to expect to roll up stressed evenly; Perhaps when the air flue number is 6, close 3 adjacent mutually air flues, then remaining 3 air flues still can guarantee to expect to roll up stressed evenly, winding off spindle can be controlled by the quantity of air bag setting for the friction force of the rewinding collar and adjust.In addition, if because some reason material is rolled up some unbalance stress, then can open and close the friction force that the rewinding collar is subjected to by the air flue of adjusting the relevant position and finely tune.
As preferred implementation, the end face of air bag 40 is provided with friction lining 41, in order to the friction force of augmented airbag 40 with the inwall of the rewinding collar 20.Different friction linings can also change the combination degree between the winding off spindle 10 and the rewinding collar 20, and the selection of friction lining can be chosen according to actual needs, repeats no more herein.
Shown in Fig. 2 (a), winding off spindle 10 outer setting of itemize rewinding unit have the rewinding collar 20, and when pneumatic supply during not to gas piping 30 inflation, air bag 40 is positioned among the groove 13.
Shown in Fig. 2 (b), when pneumatic supply during to gas piping 30 inflation, gas enters each air flue 12 by gas piping 30, and each air flue 12 and air bag 40 leak-tight joints put on the air to air bag 40.Air bag 40 after the inflation is clogged grooves 13 and to outside pushing tow, is made the friction lining 41 at its top be against the rewinding collar 20 inside, fits with the rewinding collar 20.In the use,, can adjust the combination degree of the air bag 40 and the rewinding collar 20, promptly adjust the friction force size between the two by adjusting the gaseous tension that pneumatic supply charges into gas piping 30.
Thus, the utility model has effectively been regulated the combination degree between the air bag and the rewinding collar by adjusting the size of air pressure in the gas piping, has reduced the influence that tension variation causes rewinding in the rewinding process.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; can also make some improvements and modifications, these improvements and modifications also should be considered as in the protection domain of the present utility model.
