Abstract
The invention discloses a venting roller, comprising a roller body; the center of the roller body is hollowed to form a cavity body; a plurality of blow holes are formed in the outer circumferential face of the roller body; the blow holes are tightly uniformly arrayed and at least account for a half area of the outer circumferential face of the roller body; the blow holes are communicated with the cavity body in the roller body; air inlets are formed in the circumferential faces of two ends of the roller body and are communicated with the cavity body in the roller body; and fixing supports are arranged at two ends of the roller body and are provided with fixing holes. The venting roller can effectively prevent package paper from being scraped by the face of the roller body in an overturning process.
Description
Technical field
The present invention relates to mechanical field, especially a kind of ventilation roller.
Background technology
People need to carry out the positive back face printing pattern to wrapping paper in the production process of wrapping paper, existing wrapping paper printing machine easily scratches the pattern on wrapping paper in the process of paper positive and negative of changing package, complex structure, use inconvenience, greatly reduces production efficiency.
Summary of the invention
The present invention is directed to above-mentioned deficiency a kind of ventilation roller is provided, comprise roll body, described roll body center hollow out forms a cavity, the external peripheral surface of roll body is provided with several gas holes, closely arrange uniformly and occupy at least roll body external peripheral surface 1/2 area in the described hole of blowing afloat, described gas hole is connected with the cavity in roll body, the circumferential surface at described roll body two ends is provided with air admission hole, described air admission hole is connected with the cavity in roll body, the two ends of described roll body are provided with fixed support, have fixing hole on described fixed support.
The invention has the beneficial effects as follows:, by steam vent is set on roll body, prevented that the surface that the wrapping paper stamp is crossed from contacting with roll body, thereby prevented that effectively wrapping paper pattern in switching process from being scratched by the surface of roll body.
Description of drawings
Fig. 1 is structural representation of the present invention.
1-roll body, 2-blow afloat hole, 3-air admission hole, 4-fixed support as shown in the figure.
The specific embodiment
Disclosed all features in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can make up by any way.
A kind of ventilation roller as shown in Figure 1, comprise roll body 1, described roll body 1 center hollow out forms a cavity, the external peripheral surface of roll body 1 is provided with several gas holes 2, closely arrange uniformly and occupy at least roll body 1 external peripheral surface 1/2 area in the described hole 2 of blowing afloat, described gas hole 2 is connected with the cavity in roll body 1, the circumferential surface at described roll body 1 two ends is provided with air admission hole 3, described air admission hole 3 is connected with the cavity in roll body 1, the two ends of described roll body 1 are provided with fixed support 4, have fixing hole on described fixed support 4.The present invention can prevent effectively that wrapping paper pattern in switching process from being scratched by the surface of roll body.
The present invention is not limited to the aforesaid specific embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
