Description

Technical Field

[0001] The present application relates to the technical field of printing rollers, and in particular to an oxidation-resistant and corrosion-resistant gravure printing roller. Background Art

[0002] The gravure roller is a precision tool used in the printing industry, mainly used for electronic engraving, platemaking and printing. Its characteristic is that grooves are made on the surface of the roller to carry concave and convex printing materials during the printing process. In the processing of gravure rollers, a layer of chromium is usually plated on the engraved pattern to enhance the wear resistance, oxidation resistance and corrosion resistance of the roller.

[0003] There are some problems in the use of existing gravure rollers. The gravure rollers will generate heat during use. If the gravure rollers cannot be quickly cooled and cooled, the quality of the printed products may be affected. Traditional heat dissipation methods include using water pipes and fans, but these methods have problems of low efficiency and energy waste. Therefore, the gravure rollers need to be designed with an effective heat dissipation system to maintain their normal operation. Therefore, this application proposes an antioxidant and corrosion-resistant gravure roller. Utility Model Content

[0006] Oxidation-resistant and corrosion-resistant gravure roller, including:

[0007] A roller shaft is movably sleeved with a roller and an annular gap is left between the roller and the roller shaft. End plates are slidably sleeved at both ends of the roller shaft. The end plates include a first ring plate and a second ring plate arranged coaxially. Several annularly distributed inclined plates are connected between the first ring plate and the second ring plate. Nuts are threadedly sleeved at both ends of the roller shaft and the two nuts are respectively in contact with and overlapped with the two first ring plates, and the two second ring plates are respectively in contact with and overlapped with the two ends of the roller.

[0008] Furthermore, both ends of the roller are provided with tapered grooves, and the two second ring plates are both constructed with tapered heads, and the two tapered heads are respectively plugged into the two tapered grooves.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] like Figure 1-Figure 7 As shown, an oxidation-resistant and corrosion-resistant gravure printing plate roller proposed in one embodiment of the present application includes:

[0027] The roller shaft 1 is movably sleeved with a roller 2 and an annular gap is left between the roller 2 and the roller shaft 1. The annular gap is used for ventilation to dissipate heat and cool the roller 2. End plates 3 are slidably sleeved on both ends of the roller shaft 1. The end plates 3 include a first ring plate 301 and a second ring plate 302 arranged coaxially. A plurality of annularly distributed inclined plates 303 are connected between the first ring plate 301 and the second ring plate 302. A ventilation gap is provided between two adjacent inclined plates 303 to facilitate the flow of external air into the roller 2 or the flow of air in the roller 2 to the outside. The inclined plates 303 are tilted. The plurality of inclined plates 303, the first ring plate 301 and the second ring plate 302 form an impeller of a fan. When the roller shaft 1 rotates, the two impellers rotate synchronously. The two impellers suck in (suck the outside air into the roller 2) and row (extract the air in the roller 2 to the outside), thereby generating airflow circulation, so that the airflow can pass through the roller 2. The airflow not only The roller 2 can be blown to cool it down and the heat can be quickly discharged. Both ends of the roller shaft 1 are threaded with nuts 4 and the two nuts 4 are respectively in contact with the two first ring plates 301 and the two second ring plates 302 are respectively in contact with the two ends of the roller 2. When installing the roller 2, first put the roller 2 on the roller shaft 1, then put the two end plates 3 on the two ends of the roller shaft 1 respectively, and then thread the nuts 4 on the two ends of the roller shaft 1, and then twist the two nuts 4 so that the nuts 4 squeezes and contacts the first ring plate 301, thereby forcing the two second ring plates 302 to squeeze and contact the two ends of the roller 2, thereby fixing the roller 2 to the roller shaft 1. Preferably, a spring washer sleeved on the roller shaft 1 is installed between the first ring plate 301 and the nut 4. When the nut 4 is twisted, the nut 4 squeezes the spring washer, and the spring washer exerts an elastic counter-contact force on the nut 4. The elastic counter-contact force prevents the nut 4 from rotating loose, thereby improving the stability of the fixation;

[0028] In this solution, the roller 2 is sleeved on the roller shaft 1, and then the two end plates 3 are forced to clamp and fix the roller 2 by twisting the two nuts 4, so that the gravure roller as a whole is a hollow roller. The end plate 3 is composed of a first ring plate 301, a second ring plate 302 and a plurality of inclined plates 303, so that it forms an impeller structure. When the roller shaft 1 rotates, the impeller structure formed by the two end plates 3 will produce a suction and discharge effect, thereby generating air circulation, so that the airflow can pass through the roller 2. The circulating airflow can not only blow and cool the roller 2, but also quickly conduct heat out. The mechanical energy of the rotation of the plate roller is used to achieve heat dissipation and cooling without generating additional energy consumption, thereby improving practicality.

[0029] like Figure 4 and Figure 5 As shown, in some embodiments, conical grooves 5 are provided at both ends of the roller 2, and conical heads 6 are constructed on the two second ring plates 302. The two conical heads 6 are respectively plugged into the two conical grooves 5. By providing the conical groove 5 at the end of the roller 2 and constructing the conical head 6 on the second ring plate 302 to plug into the conical groove 5, when the end plate 3 clamps the roller 2, the roller 2 and the roller shaft 1 can be quickly coaxially aligned, thereby improving the accuracy after installation.

[0030] like Figure 3 and Figure 7 As shown, in some embodiments, a first limiting groove 7 is provided at the end of the roller shaft 1, and a first limiting block 8 is constructed on the first ring plate 301 to be plugged into the first limiting groove 7. When installing the end plate 3, the first limiting block 8 on the first ring plate 301 is inserted into the first limiting groove 7, thereby improving the connection strength between the first ring plate 301 and the roller shaft 1, ensuring that the roller 2 rotates effectively and stably synchronously when the roller shaft 1 rotates.

[0031] like Figure 4 and Figure 5 As shown, in some embodiments, a second limiting groove 9 is provided on the inner wall of the conical groove 5, and a second limiting block 10 is constructed on the conical head 6 to be plugged into the second limiting groove 9. When the conical head 6 is inserted into the conical groove 5, the second limiting block 10 is inserted into the second limiting groove 9, thereby improving the connection strength between the roller 2 and the second ring plate 302, thereby ensuring the stability of the roller 2 after being fixed.

[0032] like Figure 2 and Figure 4 As shown, in some embodiments, the inner wall of the roller 2 is provided with a plurality of fins 11 distributed in a ring shape. By providing the fins 11 on the inner wall of the roller 2, the heat dissipation area is increased and the heat dissipation efficiency is improved.

[0033] like Figure 2 and Figure 4As shown, in some embodiments, the fin 11 is constructed as a spiral plate. The fin 11 is constructed as a spiral plate, so that when the roller 2 rotates, the fin 11 increases the heat dissipation area, and its spiral structure also applies horizontal thrust to the airflow, making the airflow flow more smoothly along the roller 2, further improving the heat dissipation efficiency.

[0034] like Figure 1 and Figure 6 As shown, in some embodiments, conical shells 12 are provided on opposite sides of the two second ring plates 302. Since the gravure roller is placed above the ink pool during printing and its outer peripheral side contacts the ink when rolling, the conical shell 12 can be provided so that its peripheral side surface can be placed at a certain depth in the ink without affecting the circulation of air flow, and the ink can be prevented from entering the interior of the roller 2, thereby improving practicality.

[0035] like Figure 6 As shown, in some embodiments, a sealing ring 13 is provided between the conical shell 12 and the end of the roller 2. Through the provided sealing ring 13, when the end plate 3 is installed, the conical shell 12 and the roller 2 squeeze the sealing ring 13, thereby improving the sealing of the connection point between the roller 2 and the end plate 3, preventing ink from penetrating from the connection point, and thus improving practicality.

[0036] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
