Detailed Description

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

As shown in figures 1 to 6 of the drawings,

example 1

This unreel arm dop device includes:

the bearing device comprises a cavity I1, wherein a bearing 2 is arranged at one end of the cavity I1;

the expandable chuck 4 comprises a plurality of expandable chuck components, the number of the expandable chuck components is a, the requirement that the number relation a is more than or equal to 3 is met, the expandable chuck 4 is sleeved on the outer wall of the bearing 2, a chuck cover 5 is arranged at the end part of the expandable chuck 4, and the chuck cover 5 and the bearing 4 are detachably fixed;

the rolling device 7 is characterized in that a plurality of first accommodating spaces are formed in the outer wall of the bearing 2, second accommodating spaces 71 corresponding to the first accommodating spaces in number and position are formed in the inner wall of the expandable chuck 4, and the first accommodating spaces and the second accommodating spaces 71 form accommodating cavities which are used for accommodating the rolling device.

Moreover, the bearing 2 is also provided with a rotatable shaft ring 3, and when the bearing 2 rotates, the shaft ring 3 also rotates along with the bearing, which is beneficial to the expansion of the expandable chuck under the stress.

Therefore, the utility model discloses an unreel arm dop device comprises a plurality of dops that can expand through the dop that can expand 4, and the cover is located on the outer wall of bearing 2, fixes it through the rubber band. Due to the arrangement of the rolling device, the rolling device is arranged in the accommodating space 71 formed by the outer wall of the bearing 2 and the inner wall of the expandable chuck 4.

When the unwinding arm clamping head device is used specifically, a cavity 1 of the unwinding arm clamping head device is sleeved into a 6-inch clamping head of the unwinding arm, inflation and clamping are carried out, then a 3-inch paper tube of a film roll is sleeved into an expandable clamping head 4 of the unwinding arm device, after the unwinding device of the splitting machine operates, a bearing 2 rotates, the rolling device is enabled to roll and shift, and the expandable clamping head is composed of split expandable clamping head parts, so that the expandable clamping head parts expand to a certain degree, and the clamping head and the paper tube wall of the film roll are clamped tightly.

This unreel arm dop device has following advantage when cutting: when the diameter of the film roll paper tube is converted from 6 inches to 3 inches, the 6-inch chuck does not need to be dismounted and the 3-inch chuck is replaced, only the cavity I1 of the unreeling arm chuck device needs to be sleeved with the original 6-inch chuck, the operation of dismounting and replacing the chuck from top to bottom is omitted, time and labor are saved, and the slitting efficiency is improved.

Example 2

Example 2 differs from example 1 only in that: the rolling means 7 are cylindrical. Set up columniform rolling device for in concrete working process, dop and membrane stock bobbin wall expand under the effect of the power that bearing and ball produced through the dop and press from both sides tightly, and the cutting machine operation is faster moreover, and tight power is big more tight, can not appear not pressing from both sides tight phenomenon. The phenomenon that the paper tube slides due to incomplete inflation and unclamping during air inflation clamping is effectively avoided, unqualified products are reduced, and the product percent of pass is effectively improved.

Example 3

Example 3 differs from example 1 only in that: the number of expandable chuck members is three, namely expandable chuck member one 41, expandable chuck member two 42 and expandable chuck member three 43.

The outer diameter of the expandable chuck 4 corresponds to the diameter of the paper tube roll of the film by 3 inches, and when the expandable chuck is used specifically, the paper tube roll of the film by 3 inches is sleeved on the outer wall of the expandable chuck 4.

Example 4

Example 4 differs from example 1 only in that: bolt holes 51 which are uniformly arranged are formed in the chuck cover 5, and bolt holes two 21 which correspond to the bolt holes 51 one by one are formed in the bearing 2.

During specific assembly:

step 1

And the cavity I1 and the bearing 2 are screwed and fixed by a fixing bolt I6, and then the bottom of the fixing bolt I6 is welded with the cavity I1.

Step 2

A rotatable shaft ring 3 is fitted into a bearing 2, and a first expandable chuck member 41, a second expandable chuck member 42 and a third expandable chuck member 43 of a chuck 4 are combined into a cylindrical expandable chuck 4 by a rubber ring, and then fitted into the bearing 2.

Step 3

Put into cylindrical rolling device 7 in dop 4 and bearing 2's space, put it in the little circular arc position of each component part of dop 4, then cover dop lid 5, correspond the location with bolt hole two 21 on bolt hole 51 on the dop lid 5 and the bearing 2 in proper order, the rethread is put into fixing bolt two 511 and is realized that the dop lid 5 can dismantle with the bearing fixed, specifically be connected with the bolt hole 21 of bearing 2 through the bolt hole 51 of dop lid 5 and screw fixedly, so just assembled the utility model discloses an unreel arm dop device, this dop device is used for placing of 3 inches film paper tube during the use.

Example 5

Example 4 differs from example 1 only in that: the first cavity 1 has an outer diameter of 6 inches and the expandable collet 4 has an outer diameter of 3 inches.

When cutting, when membrane stock form pipe diameter converted to 3 inches from 6 inches, need not to lift 6 inches dops off and change 3 inches dops, only need with the utility model discloses a 3 inches dop device embolia original 6 inches dops can, saved the dop and dismantled the change operation from top to bottom, save time and laborsaving, improved and cut efficiency.

The preferred embodiments of the present invention are described herein, but the scope of the present invention is not limited thereto.
