The purpose of this utility model is to provide a kind of alter device of writing of the renewable core that can overcome the above-mentioned shortcoming of prior art, this alter device of writing has disposable facility, lower than its cost again, specifically, just provide a kind of novel alter device of writing, it is altered volume and is made in the tape, alter volume use up the back directly change this tape just can, and need not carry out complicated change of lap work.

The purpose of this utility model is to realize like this, construct a kind of alter device of writing of renewable core, comprise shell and cased tape drum, described shell comprises outer casing upper cover 1, shell lower cover 15 and the take-up gear 14 that is contained on the shell lower cover 15, the take-up splined shaft 11 coaxial with take-up gear 14, with take-up gear 14 engagement for band gear 13 and with for band gear 13 coaxial for band splined shaft 12, offer dial hole 16 and observation window 2 on the described outer casing upper cover 1, tape drum is made up of loam cake 3 and lower cover 10, tape drum loam cake 3 is provided with interior dial hole 19, interior observation window 17 dial hole 16 with described outer casing upper cover 1 respectively is relative with observation window 2, on tape drum lower cover 10, be provided with for belt carcass 6 and the knob 5 coaxial with it, on tape drum lower cover 10, also be provided with take-up core 4 and lead 9, for being equipped with on the belt carcass 6 without correction volume (correction tape) 8 that uses, alter volume 8 process leads 9 and pressing head 7 at last around to take-up core 4, described on belt carcass 6 and the shell lower cover 15 for 12 engagements of band splined shaft, described take-up core 4 can with 11 engagements of take-up splined shaft.

The renewable core that provides according to the utility model write alter device, it is characterized in that, also be provided with a plurality of reference columns 18 that are used for the tape drum location at described outer casing upper cover 1 and shell lower cover 15 inwalls, the outside of described tape loam cake 3 and lid lower cover 10 is respectively equipped with the locating hole 20 that can cooperate with outer casing inner wall reference column 18.

Implement the alter device of writing of renewable core that the utility model provides, have disposable facility, change of lap that need not be complicated is low than disposable expense again, because the design of shell and running part is reusable, thereby obtaining perfectly taking into account aspect economy and the efficient.

In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present utility model, in the accompanying drawing:

Fig. 1 is the decomposition texture schematic diagram of writing alter device of the renewable core that provides of the utility model.

As shown in Figure 1, the alter device of writing of the renewable core that the utility model provides comprises shell (1,15) and the cased tape drum (2,10) of altering volume that is equipped with, and shell comprises outer casing upper cover 1, shell lower cover 15 and is contained in transmission device (11,14,13,15) on the shell lower cover 15.Offer dial hole 16 and observation window 2 on the outer casing upper cover 1, observation window 2 is used for observing tape drum from housing exterior and alters band in the surplus that supplies on the belt carcass 6.The knob 5 that dial hole 16 is used for seeing through on this dial hole rotation tape drum furls tightly the correction that supplies on the belt carcass 6.Transmission device on the shell lower cover 15 comprise take-up gear 14, with the coaxial take-up splined shaft 11 of take-up gear 14, for band splined shaft 12 and with for band splined shaft 12 coaxial for band gear 13, take-up gear 14 is engaged with each other with supplying band gear 13, but plug-in mounting is wound with the confession belt carcass 6 of still untapped correction volume on the confession band splined shaft 12, but plug-in mounting twines the tape drum take-up core 4 of already used correction volume on the take-up splined shaft 11, also is provided with a plurality of reference columns 18 that are used for the tape drum location at outer casing upper cover 1 and shell lower cover 15 inwalls.Tape drum is made up of loam cake 3 and lower cover 10, tape drum loam cake 3 is provided with interior dial hole 19, the dial hole 16 with outer casing upper cover 1 is relative with observation window 2 respectively for interior observation window 17, the outside of tape loam cake 3 and lid lower cover 10 is respectively equipped with the locating hole 20 that can cooperate with outer casing inner wall reference column 18, on tape drum lower cover 10, be provided with for belt carcass 6 and the knob 5 coaxial with it, for being equipped with on the belt carcass 6, alter volume 8 process leads 9 and pressing head 7 at last around to take-up core 4 without correction volume (correction tape) 8 that uses.Be with splined shaft 12 engagements for supplying on belt carcass 6 and the shell lower cover 15, thereby feed wheel 6 rotations are by supplying to be with splined shaft 12 drives to rotate and can will be wound up with the correction band of crossing by the take-up core 4 in the pressing head 7 driving tape drums for band gear 13.The each use, the correction volume part that is on the pressing head 7 can be coated with on the part that is pressed onto the desire modification, simultaneously, will produce, after all the correction band uses up for the untapped correction band on the belt carcass, whole tape can be abandoned, because running part is located in the shell, and abandoned tape cost is lower, and abandons the existing integrated alter device of writing after each the use and compares, institute increases cost seldom, has but improved operating efficiency greatly.

Be provided with two curved booms 21 for band gear 13, when supplying band gear 13 works to rotate, can slip over the ring slot 22 that is located on shell lower cover 15 inwalls, and when reverse rotation, then play certain interception, to guarantee supplying belt carcass 6 can not become flexible for the band direction.
