Abstract
The utility model discloses an air-breathing foil feeding mechanism for a rotary hot stamping machine, which is formed by a foil feeding roller and a control air circuit for the foil feeding roller. The foil feeding roller comprises a central spindle with a cavity and a sleeve roller capable of rotating around the central spindle; an air port is arranged in the cavity wall of the central spindle at an effective angle alpha; an air inlet hole communicated with the cavity is arranged in one end face of the central spindle; a plurality of pinhole air holes are uniformly distributed in the surface of the sleeve roller; the control air circuit is communicated with the cavity of the central spindle; and the control air circuit comprises a vacuum air source, a pressure reducing valve, an electromagnetic valve and a cylinder current limiter which are sequentially connected. The air-breathing foil feeding mechanism disclosed by the utility model effectively solves the problems of wear of a pressure roller type foil feeding mechanism, damage to an alumite transfer print layer and the like.
Description
Technical field
The utility model relates to this patent and relates to a kind of thermoprinting machine, particularly a kind of air suction type foil feeding mechanism that is used for circle pressure circle thermoprinting machine.
Background technology
As the core institution of automatic thermoprinting machine, the foil feeding mechanism of electrochemical aluminum foil has determined the quality of the whole thermoprint quality of machine, and traditional foil feeding mechanism is a pinch roller formula (see figure 1).This foil feeding mechanism will be sandwiched in through the friction force that relatively rotates generation that send paper tinsel roller 1 and pinch roller 2 and send paper tinsel roller 1 and the electrochemical aluminum foil 3 in the middle of the pinch roller 2 to see off.Send the size of the friction force between paper tinsel roller 1 and the pinch roller 2 to determine the feed accuracy of electrochemical aluminum foil 3; Skidding can take place in the too small electrochemical aluminum foil 3 of friction force; The excessive wearing and tearing that then can quicken pinch roller 2 rubber toppings, and to the generation of the transfer printing layer on the electrochemical aluminum foil 3 of contact with it destruction.In addition, owing to send paper tinsel roller 1 to place machine intimate, the regulating spring 4 of adjustment friction force uses cumbersome, and adjustment and inconvenient.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, and a kind of air suction type foil feeding mechanism that circle is pressed the circle thermoprinting machine that is used for is provided, and it has effectively been avoided the wearing and tearing of pinch roller formula foil feeding mechanism and has destroyed problem such as electrochemical aluminium transfer printing layer.
The technical scheme that realizes above-mentioned purpose is: a kind of air suction type foil feeding mechanism that is used for circle pressure circle thermoprinting machine is to be made up of a control gas circuit of sending paper tinsel roller and to send the paper tinsel roller, wherein:
Said mandrel that send the paper tinsel roller to comprise to be with cavity and the cover roller that can rotate around mandrel offer gas port at an effective angle α on the chamber wall of said mandrel, offer on the end face of said mandrel one be communicated with said cavity induction opening; Be uniformly distributed with a plurality of pin hole cores on the surface of said cover roller;
Said control gas circuit is communicated with the cavity of said mandrel, and this control gas circuit comprises bonded assembly vacuum source, reducing valve, electromagnetic valve and cylinder current limiter successively.
Above-mentioned be used for the air suction type foil feeding mechanism that circle is pressed the circle thermoprinting machine, wherein, said control gas circuit is communicated with the cavity of said mandrel through the inlet suction port that is installed on the induction opening of said mandrel.
The technical scheme of the air suction type foil feeding mechanism that is used for circle pressure circle thermoprinting machine of the utility model; Carried out design again through the structure that will send the paper tinsel roller; Make and send the paper tinsel roller to be the regional air-breathing of electrochemical aluminum foil contact; Consequent adsorption affinity inhales electrochemical aluminum foil in the surface of sending the paper tinsel roller, is seen off along with the rotation of sending the paper tinsel roller makes electrochemical aluminum foil, has effectively avoided the wearing and tearing of pinch roller formula foil feeding mechanism and has destroyed problems such as electrochemical aluminium transfer printing layer.The utility model the air suction type foil feeding mechanism simple in structure, be easy to the adjustment.

The specific embodiment
In order to understand the technical scheme of the utility model better, below through embodiment particularly and combine accompanying drawing at length to explain:
See also Fig. 2, Fig. 3 a and Fig. 3 b, the air suction type foil feeding mechanism that is used for circle pressure circle thermoprinting machine of the utility model is to be made up of a control gas circuit of sending paper tinsel roller 5 and to send the paper tinsel roller.
See also Fig. 4 again, send the control gas circuit of paper tinsel roller to be communicated with the cavity of mandrel 51 through inlet suction port 53, this control gas circuit comprises bonded assembly vacuum source 6, reducing valve 7, electromagnetic valve 8 and cylinder current limiter 9 successively.
The circle that is used for of the utility model presses the principle of work of the air suction type foil feeding mechanism of circle thermoprinting machine to be: electrochemical aluminum foil 3 is around the surface of sending paper tinsel roller 5; When cover roller 52 rotates; The core of gas port 511 positions of its corresponding mandrel 51 can both be air-breathing and produce adsorption affinity; Play in the air-breathing effect of effective angle with this, consequent adsorption affinity inhales electrochemical aluminum foil 3 in the surface of sending paper tinsel roller 5, is seen off along with the rotation of sending paper tinsel roller 5 makes electrochemical aluminum foil 3.Can adjust the adsorption affinity that send paper tinsel roller 5 surfaces through regulating reducing valve 7 easily with cylinder current limiter 9.Element on the control gas circuit can be installed in the integrated gas circuit cabinet in the thermoprinting machine outside, regulates very convenient.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
