A kind of colour band adjustment structure of hot coding machine
Technical field
The utility model belongs to field of mechanical technique, relates to the colour band adjustment structure of a kind of hot coding machine, particularly a kind of hot coding machine.
Background technology
The equipment that corresponding ink marks is stayed on the soft package material product with the printing ink on the number after the heating or the letter fusing colour band is called hot coding machine.Because easy to clean when using, the characteristics that the printing ink cooling is namely done are widely used in industries such as food, medicine.Present colour band hot coding machine is by compositions such as loose wheel, driving original paper, number seat, live-roller, pressure roller, take-up pulley and tape guide rollers.The effect of live-roller and pressure roller is that colour band is pressed in the middle of it, makes colour band make regular equidistant step motion under the rotation of live-roller, and the colour band of not printing is moved under the number, and the colour band of printing is then rolled by take-up pulley.
This coder can only be operated the colour band of identical size because the loose wheel size of placement colour band is fixing, has certain limitation, after the width adjustment of colour band, this coder then can not be worked, and needs other coder, has so just increased cost.If by force wideer colour band is put in this coder, colour band can be out of shape, thereby influences the printing effect of colour band.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of colour band adjustment structure that makes hot coding machine can adapt to the hot coding machine of different colour bands.
The purpose of this utility model can realize by following technical proposal:
A kind of colour band adjustment structure of hot coding machine, comprise the rotating shaft that is used for placing the colour band wheel that is vertical on the motherboard, it is characterized in that, have stop part and positioning step in the described rotating shaft, described stop part place is fixed with fixed dam, be arranged with sleeve on the described positioning step, the described sleeve outside is connected with the sideboard that is oppositely arranged with the said fixing baffle plate, and also has in the described rotating shaft for the fixture that sleeve is fixed in the rotating shaft.When the colour band wheel was set in this rotating shaft, fixed dam was resisted against the inboard of colour band wheel, and sideboard is resisted against the outside of colour band wheel.
In the colour band adjustment structure of above-mentioned hot coding machine, the outer end of described rotating shaft has external screw thread, and above-mentioned fixture comprises the nut that is set on this external screw thread, and the inboard of described nut is resisted against on the above-mentioned sleeve.
In the colour band adjustment structure of above-mentioned hot coding machine, vertically be provided with guide post on the described motherboard, be arranged with the fixedly back-up ring with the corresponding setting of said fixing baffle plate on the described guide post, also be arranged with the movable back-up ring with the corresponding setting of above-mentioned sideboard on the described guide post, described guide post is provided with for adjusting activity back-up ring with respect to the fixing regulon of back-up ring position.
In the colour band adjustment structure of above-mentioned hot coding machine, described regulon comprises the external screw thread that is positioned at the guide post outside and the internal thread that is positioned at movable back-up ring inboard, and described external screw thread and internal thread are complementary.
When being arranged with the colour bands wheel of different sizes in the rotating shaft, need regulate the movable back-up ring on the guide post, rotate this activity back-up ring, make movable back-up ring and fixedly between the back-up ring apart from colorimetric bandwidth 1mm.
Compared with prior art, the colour band adjustment structure of this hot coding machine has the following advantages:
This adjustment structure is used for hot coding machine, can strengthens the applicability of hot coding machine, can mate the colour band of multiple different sizes, reduce the use to the hot coding machine of different model, save production cost; The reasonable in design of this adjustment structure, installation and easy to operate, long service life.
Description of drawings
Fig. 1 is the structural representation of a kind of preferred embodiment of providing of the utility model.
Among the figure, 1, motherboard; 2, rotating shaft; 21, stop part; 22, sleeve; 3, fixed dam; 4, sideboard; 5, fixture; 6, guide post; 7, fixing back-up ring; 8, movable back-up ring.
The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
The colour band adjustment structure of hot coding machine as shown in Figure 1, it comprises the rotating shaft 2 that is used for placing the colour band wheel that is vertical on the motherboard 1, have stop part 21 and positioning step in the rotating shaft 2, stop part 21 places are fixed with fixed dam 3, in the present embodiment, fixed dam 3 is by being bolted on this stop part 21.
As shown in Figure 1, be arranged with sleeve 22 at positioning step, sleeve 22 outsides are connected with the sideboard 4 that is oppositely arranged with fixed dam 3, and also have in the rotating shaft 2 for the fixture 5 that sleeve 22 is fixed in the rotating shaft 2.When the colour band wheel was set in this rotating shaft 2, fixed dam 3 was resisted against the inboard of colour band wheel, and sideboard 4 is resisted against the outside of colour band wheel.
Concrete, as shown in Figure 1, the outer end of rotating shaft 2 has external screw thread, and fixture 5 comprises the nut that is set on this external screw thread, and the inboard of nut is resisted against on the sleeve 22.
As shown in Figure 1, on motherboard 1, also vertically be provided with guide post 6, be arranged with the fixedly back-up ring 7 with fixed dam 3 corresponding settings on the guide post 6, also be arranged with the movable back-up ring 8 with sideboard 4 corresponding settings on the guide post 6, guide post 6 is provided with for adjusting activity back-up ring 8 with respect to the fixing regulon of back-up ring 7 positions.
As shown in Figure 1, this regulon comprises the external screw thread that is positioned at guide post 6 outsides and is positioned at the internal thread of movable back-up ring 8 inboards that external screw thread and internal thread are complementary.
When being arranged with the colour bands wheel of different sizes in the rotating shaft 2, need regulate the movable back-up ring 8 on the guide post 6, rotate this activity back-up ring 8, make movable back-up ring 8 and fixedly between the back-up ring 7 apart from colorimetric bandwidth 1mm.
This adjustment structure is used for hot coding machine, can strengthens the applicability of hot coding machine, can mate the colour band of multiple different sizes, reduce the use to the hot coding machine of different model, save production cost; The reasonable in design of this adjustment structure, installation and easy to operate, long service life.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used motherboard 1, rotating shaft 2, stop part 21, sleeve 22, fixed dam 3, sideboard 4, fixture 5, guide post 6, fixing term such as back-up ring 7, movable back-up ring 8 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
