Abstract
The utility model discloses a waist-dump shaped bronzing roller and resolves a technical problem that middle indentation light hot stamping effect is breezing easily in an existing bronzing roller stamping process. The waist- dump shaped bronzing roller comprises a roller body (2). A roller shaft (1) is respectively fixed on the two ends of the roller body (2). The roller body (2) is a waist-dump shape which is thick in center and thin at two ends. The middle diameter of the roller body (2) is larger than the diameters of the both ends of the roller body (2) by 0.3-0.6 millimeter. The waist-dump shaped bronzing roller is simple in structure, reduces rejection rate of printing products in a printing factory greatly, and brings better economic benefits for users.
Description
Technical field
The utility model relates to the roller of using in a kind of printing equipment, the gold stamping roller of particularly using in a kind of printing equipment.
Background technology
Traditional gold stamping roller is middle to be identical with the diameter on both sides, on the roll shaft of both sides, to exert pressure in use, gold stamping roller and rubber roll all can produce certain flexural deformation after pressing, but both distortion are just in time opposite, therefore the place in the middle of both can form the slit of certain width, impression is light in the middle of showing after scalding, hot stamping effects is apprehensive, and this phenomenon can be more serious along with the horizontal lengthening of pattern, and percent defective is improved, and causes waste.
Summary of the invention
The utility model provides a kind of dolioform gold stamping roller, has solved existing gold stamping roller and the apprehensive technical problem of the middle light hot stamping effects of impression easily occurs when thermoprint.
The utility model is by the above problem of following solution:
A kind of dolioform gold stamping roller comprises roll body, all is fixedly installed roll shaft at the two ends of roll body, and roll body is thin ends and thick middle swelling-waist shape.
The mid diameter of described roll body is than the large 0.3-0.6 millimeter of two ends diameter of described roll body.
The utility model is simple in structure, greatly reduces the percent defective of printing house print product, for the user has brought preferably economic benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of dolioform gold stamping roller comprises roll body 2, all is fixedly installed roll shaft 1 at the two ends of roll body 2, and roll body 2 is thin ends and thick middle swelling-waist shape.
The mid diameter D of described roll body 2 is than the large 0.3-0.6 millimeter of two ends diameter d of described roll body 2.
Intermediate sizes of the present utility model is than the large 0.3-0.6 millimeter in both sides, structure for swelling-waist shape, in use, plus-pressure on the roll shaft of both sides, gold stamping roller and rubber roll all produce certain flexural deformation, size high in the middle and low on both ends just in time remedies the deflection that produces because of pressure, gold stamping version version and rubber roll contact-making surface are coincide well, scald rear because of contact position pressure uniformity, therefore hot stamping effects has reached uniformity, the phenomenon that the pattern impression that prevents centre and both sides pressure inequality and occur and thickness effect differ has greatly reduced the wasting phenomenon in producing.
Claims (2)
1. a dolioform gold stamping roller comprises roll body (2), all is fixedly installed roll shaft (1) at the two ends of roll body (2), it is characterized in that, roll body (2) is thin ends and thick middle swelling-waist shape.
2. a kind of dolioform gold stamping roller according to claim 1 is characterized in that, the mid diameter (D) of described roll body (2) is than the large 0.3-0.6 millimeter of two ends diameter (d) of described roll body (2).
