Abstract
The utility model discloses a locking and clamping type holding device for reducing damage of inner layer roll paper. The locking and clamping type holding device for reducing the damage of the inner layer roll paper comprises a fixed plate (1) and a central spindle. The fixed plate (1) and the central spindle are coaxially arranged, and the central spindle is a step central spindle and comprises at least two central spindles with different diameters. Due to the fact that the locking and clamping type holding device for reducing the damage of the inner layer roll paper adopts a step central spindle structure, the device is made to be capable of being suitable for matching of roll paper barrels with different central spindle bore diameters, the matching is suitable and balanced, no supporting and expanding force is generated to central spindle holes, and no damage can be generated to inner layer paper of the roll paper. The defects that in the prior art a wedge-shaped holding device is prone to damaging the inner layer of the roll paper due to the existence of the supporting and expanding force and waste and loss are caused are overcome. When the locking and clamping type holding device for reducing the damage of the inner layer roll paper is used, central spindles with different diameters can be used according to sizes of the core tube of the roll paper, and the core tube of the roll paper and the inner layer paper can be effectively prevented from being broken due to expansion. The locking and clamping type holding device for reducing the damage of the inner layer roll paper has the advantages of being simple in structure, easy to operate, and beneficial for using tail paper of the roll paper.
Description
Technical field
The utility model belongs to the printing equipment technical field, is specifically related to a kind of card-locked type holding device that helps to reduce the damage of internal layer coil paper.
Background technology
No matter be papermaking or printing, individual of the traditional sense that all has been through with copied paper, the history of sheet-fed printing, entered the industrialized production epoch already, therefore, the carrying of reel paper tape, transfer, and the paper tape in the printing carries, accepts, and all needs the operation with the clamping paper in reel.Mostly the holding device of prior art is wedge structure, its advantage is the cooperation that can adapt to the paper in reel in different mandrels aperture automatically, but shortcoming also is very outstanding, because wedge structure, the mandrel aperture there is the effect of rising of supportting, consequently tears the core tube, so the internal layer paper tape, cause tail paper to use difficulty, tail paper condemnation factor is more than 2.5 ‰.For this reason, develop a kind of simple in structurely, easy and simple to handle, the card-locked type holding device that can adapt to different mandrel coil papers is the keys that overcome the prior art deficiency.
The utility model content
It is a kind of simple in structure, easy and simple to handle that the purpose of this utility model is to provide, and can adapt to the card-locked type holding device that can reduce the damage of internal layer coil paper of different mandrel coil papers.
The purpose of this utility model realizes that like this comprise reaction plate and mandrel, described reaction plate is the step mandrel with the coaxial setting of mandrel, described mandrel, comprises two mandrels that diameter is different at least.
The utility model adopts step mandrel structure, makes the chart drum that can adapt to different mandrels aperture cooperate, and cooperates proper, balance, can not produce the support tension to the mandrel hole, can not produce infringement to the internal layer paper of coil paper.Overcome the existence of the wedge shape holding device of prior art because of the support tension, easily the internal layer to coil paper causes damage, causes the drawback of waste and loss.Can use the mandrel of different-diameter during use according to coil paper core tube size, effectively avoid coil paper core tube and internal layer paper to be bursting at the collision.The utlity model has simple in structurely, easy and simple to handle, help to make full use of the advantage of reel tail paper.
Description of drawings
Fig. 1 is the utility model integral structure scheme drawing;
Fig. 2 is the utility model working state schematic representation;
Among the figure: 1-reaction plate, 2-pivot shaft, the big mandrel of 3-, mandrel among the 4-, 5-small core shaft, 6-lock pin, 7-draw-in groove, 8-coil paper.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but never in any form the utility model is limited, and any conversion based on the utility model training centre is done all falls into the utility model protection domain.
As shown in Figure 1, the utility model comprises reaction plate 1 and mandrel, and described reaction plate 1 is the step mandrel with the coaxial setting of mandrel, described mandrel, comprises two mandrels that diameter is different at least.
Described step mandrel is divided into three grades, comprises big mandrel 3, middle mandrel 4 and small core shaft 5 successively.
A lock pin 6 is set on each grade mandrel of described step mandrel at least.
Described reaction plate 1 outside also is provided with pivot shaft 2.
On the described pivot shaft 2 draw-in groove 7 is set,, realizes spacing rotation to cooperate with bayonet lock.
Described lock pin 6 and spacing cooperation of mandrel pedestal elasticity.
Described lock pin 6 is cylindrical or spheroidal.
Each grade leading edge of described step mandrel is provided with rounding, is connected to adapt to coil paper mandrel hole.
Principle of work of the present utility model and working process:
The utility model adopts step mandrel structure, makes the chart drum that can adapt to different mandrels aperture cooperate, and cooperates proper, balance, can not produce the support tension to the mandrel hole, can not produce infringement to the internal layer paper of coil paper.Overcome the existence of the wedge shape holding device of prior art because of the support tension, easily the internal layer to coil paper causes damage, causes the drawback of waste and loss.Can use the mandrel of different-diameter during use according to coil paper core tube size, effectively avoid coil paper core tube and internal layer paper to be bursting at the collision.
During use, only need the internal diameter according to the paper core axis hole, the suitable mandrel of socket the utility model step mandrel get final product, and the draw-in groove on the pivot shaft can suspension hook or lifting rope cooperation, and is easy and simple to handle.
